The traditional graphic system refers to the graphics and plotting functions in base R. For example, although ggplot2 is currently probably the most popular R package for doing presentation quality plots it does not offer 3D plots. To work effectively in R I think it is necessary to know your way around at least two of the graphics systems.

But back to the relatively tame task of 3D plots: the generic function persp in the base graphics package draws perspective plots of a surface over the x—y plane. Typing demo persp at the console will give you an idea of what this function can do. The plot3D package from Karline Soetaert builds on on persp to provide functions for both 2D and 3D plotting. The vignette for plot3D shows some very impressive plots.

Load the package and type the following commands at the console: example persp3Dexample surf3D and example scatter3D to see examples of 3D surface and scatter plots.

Also, try this code to see a cut-away view of a Torus. The vignette for this package is shows a rich array of plots. The lattice package has its own distinctive look.

Once you see one lattice plot it should be pretty easy to distinguish plots made with this package from base graphics plots. Load the packate and type example cloud in the console to see a 3D graph of a volcano, and 3D surface and scatter plots. Load the rgl package and type example plot3d to see a very cool, OpenGL, 3D scatter plot that you can grab with your mouse and rotate.

In addition to the x, y and z values, an additional data dimension can be represented by a color variable argument colvar. The package plot3Drgl allows to plot easily the graph generated with plot3D in openGL, as made available by package rgl.

This is described at the end of the present article. The species are Iris setosa, versicolor, and virginica. The argument clab is used to change the title of the color legend. By default, the points are colored automatically using the variable Z.

The argument side is used to specify the colkey position: 1: for bottom, 2: for left, 3: for top, 4: for right. The arguments theta and phi can be used to define the angles for the viewing direction. The argument CI is used. If CI is a list, it should contain at least the item x, y or z latter for scatter3D.

The list should include at least x, y, z, defining the surface. Other optional parameters can be specified in the surf argument including: colvar, col, NAcol, border, facets, lwd, resfac, clim, ltheta, lphi, shade, lighting, fit. Note that, the function expand. Note that, in order to choose suitable ranges for zooming, you can display axis ranges as follow:. Prepare the data: we want to plot 4 arrows starting from the point of coordinates c x0, y0, z0 and ending at c x1, y1, z1.

Note that, segments3D and segments2D are very similar to arrows3D and arrows2D and you can play with them also. To draw an interactive 3D plot the package plot3Drgl can be used. The package plot3Drgl allows to plot the graph generated with plot3D in openGL, as made available by package rgl. The package rgl allows to interactively rotate, zoom the graphs. This analysis has been performed using R software ver. Install plot3D package Load plot3D package Prepare the data Scatter plots Functions for scatter plots and texts in 2D and 3D Basic scatter plot Change the type of the box around the plot Color palettes Change the color by groups Change the position of the legend 3D viewing direction Titles and axis labels Tick marks and labels Add points and text to an existing plot Line plots Add confidence interval 3D fancy Scatter plot with small dots on basal plane Regression plane text3D: plot 3-dimensionnal texts text3D and scatter3D 3D Histogram scatter2D: 2D scatter plot text2D Other functions Interactive plot Infos.

To be more specific, the article looks as follows:. Our data consists of two numeric vectors x and y1. The vector x contains a sequence from 1 to 10, y1 contains some random numeric values.

Have a look at the following R code:. Based on Figure 1 you can also see that our line graph is relatively plain and simple. So keep on reading!

Note that you may use any Hex color code or the predefined colors in R to change the color of your graphics. We can increase or decrease the thickness of the lines of a line graphic with the lwd option as follows:. In this example, we used an lwd of By increasing this number, the thickness is getting larger, and by decreasing this number the line is becoming thinner.

Note that the line thickness may also be changed, when exporting your image to your computer. It is possible to add points to visualize the underlying data of our line plot even better. In this example I want to show you how to plot multiple lines to a graph in R. First, we need to create further variables for our plot:. Furthermore, we may add a legend to our picture to visualize which color refers to which of the different variables.

Figure 6 shows the output of the R code of Example 6.

We created a graph with multiple lines, different colors for each line, and a legend representing the different lines. With the pch argument we can specify a different point symbol for each line. Figure 7: Change pch Symbols of Line Graph. So far, we have only used functions of the base installation of the R programming language. However, there are many packages available that provide functions for the drawing of line charts. One of the most powerful packages for the creation of graphics is the ggplot2 package.

We can install and load the ggplot2 package with the following two lines of R code:. Furthermore, we need to store our data in a data frame, since the ggplot2 package is usually based on data frames:.

The RStudio console is showing how our new data is structured. Our data frame contains three columns and 30 rows. The first column contains of our x values i. Figure 8: Create Line Chart with ggplot2 Package. Figure 8 is showing how a ggplot2 line graph looks like. Of cause, the ggplot2 package is also providing many options for the modification of line graphics in R.

You learned in this tutorial how to plot lines between points in the R programming language.You can report issue about the content on this page here Want to share your content on R-bloggers? Plotly is a platform for data analysis, graphing, and collaboration. Now, you can you can also make 3D plots. Immediately below are a few examples of 3D plots.

First, let's convert a ggplot2 tile plane into a Plotly graph, then convert it to a 3D plot. You can copy and paste this code and use a test username and key, or sign up for an account and generate your own. We return a URL: plot. The URL hosts the interactive plot, rendered with D3.

We can export or embed plots in Shiny Apps, knitr, Slidify, blogs, and in an iframe, as we're doing below. We'll now style, share, and change to 3D in the web app.

The web app runs online and is free, so you won't need to install or download anything. Below is our edited plot. Go to the plot and press " View full-size graph" to really dig in, or go straight to a full-screen version: plot.

Try clicking, holding, and toggling to flip, drag, and zoom. Press the icons in the upper right-hand corner to change modes. We can also use qplot and edit the plot in the GUI.

Assuming you ran the code above:. Or combine data from another plot. Privacy settings are like Google Drive and GitHub: you control if plots are public or private, you own your data and can add collaborators, or you can run Plotly on-premise. For example, try this code to make a surface plot. Plotly also supports 3D line and scatter plots.

Editing in the GUI offers options for editing the lighting, lines that appear when hovering, colors in the scene and grid lines, and axis titles. The plot, as well as code to reproduce our new version, is also available at the URL: plot. You can also plot a random walkthe Lorenz attractorfunctions, and stock volatility.

### Plot Line in R (8 Examples) | Create Line Graph & Chart in RStudio

When I searched on the internet, I found that this message happens when combinations of X and Y values are not unique. But here they are unique. I tried some other libraries and there it works without problems. But I don't like the default style of the plots the built-in functions should fulfill my expectations.

### 3D Scatter Plots in R

If you're working with "real" data for which the grid intervals and sequence cannot be guaranteed to be increasing or unique hopefully the x,y,z combinations are unique at least, even if these triples are duplicatedI would recommend the akima package for interpolating from an irregular grid to a regular one. Note that the default grid to which your data is mapped to by akima::interp is defined by 40 equal intervals spanning the range of x and y values:.

But of course, this can be overridden by passing arguments xo and yo to akima::interp. I use the lattice package for almost everything I plot in R and it has a corresponing plot to persp called wireframe.

Let data be the way Sven defined it. Or how about this modification of fig 6. Since this post continues to draw attention I want to add the OpenGL way to make 3-d plots too as suggested by tucson below. First we need to reformat the dataset from xyz-tripplets to axis vectors x and y and a matrix z. This image can be freely rotated and scaled using the mouse, or modified with additional commands, and when you are happy with it you save it using rgl.

Adding to the solutions of others, I'd like to suggest using the plotly package for Ras this has worked well for me. Below, I'm using the reformatted dataset suggested above, from xyz-tripplets to axis vectors x and y and a matrix z:.

The rendered surface can be rotated and scaled using the mouse. This works fairly well in RStudio. Not sure why the code above did not work for the library rglbut the following link has a great example with the same library. Run the code in R and you will obtain a beautiful 3d plot that you can turn around in all angles. Learn more. Plot 3D data in R Ask Question.

Classic List Threaded. Karl Brand. Duncan Murdoch Re: create a '3D line plot'. David Winsemius. In reply to this post by Karl Brand.

In reply to this post by Duncan Murdoch All excellent, runable examples helping me progress quickly. Being more a qualitative plot, the y-axis is less important. But it did get me thinking- Coloring each of the plotted lines, say 'altitude colors' like the classic volcano example to reflect the scaled values the lines represent might be effective at representing individual y-axis magnitude for each line.

Perhaps gray background at least. Maybe if there were examples of the lines func. Or some one already made a function for achieving this? Google didnt return anything obvious for me Some features of scales are still a bit beyond me All in all, for a few lines of code, it's a pretty decent plot, even though it needs some work.

**4D XYZ Plot With Custom Boundary**

Thank Hadley for that Jim Lemon. You can draw it by using polygon to hide the background then lines to draw the lines. In reply to this post by Duncan Murdoch-2 Cheers! Free forum by Nabble. Edit this page.I recently posted an article describing how to make easily a 3D scatter plot in R using the package scatterplot3d.

This R tutorial describes how to perform an interactive 3d graphics using R software and the function scatter3d from the package car. The function scatter3d uses the rgl package to draw and animate 3D scatter plots. Note that, on Linux operating system, the rgl package can be installed as follow:. The species are Iris setosa, versicolor, and virginica. Note that, the plot can be manually rotated by holding down on the mouse or touchpad.

Note that, the display of the surface s can be changed using the argument fit. The argument surface. For multi-group plotsthe colors are used for the regression surfaces and for the points in the several groups. By default, different colors are used for the 3 axes. The argument axis.
