Just for fun with the help of other stackoverflowers. I put together start to finish code of a hypothetical experiment with ten measurement replicated three times. In the arrows(.) function length=0.05 is the size of the "arrowhead" in inches, angle=90 specifies that the "arrowhead" is perpendicular to the shaft of the arrow, and the particularly intuitive code=3 parameter specifies that we want to draw an arrowhead on both ends of the arrow.įor horizontal error bars the following changes are necessary, assuming that the sdev vector now contains the errors in the x values and the y values are the ordinates: plot(x, y,Īrrows(x-sdev, y, x+sdev, y, length=0.05, angle=90, code=3) # hack: we draw arrows but with very special "arrowheads"Īrrows(x, avg-sdev, x, avg+sdev, length=0.05, angle=90, code=3) Main="Scatter plot with std.dev error bars" Pch=19, xlab="Measurements", ylab="Mean +/- SD", Using these, here come the plotting commands: plot(x, avg, Let's make the abscissa just the number of these "measurements", so x <- 1:n. Let's assume you have a vector of "average values" avg and another vector of "standard deviations" sdev, they are of the same length n. This not-so-straightforward idea comes from the R Wiki Tips and is reproduced here as a worked-out example. The trick is to draw arrows (!) but with little horizontal bars instead of arrowheads (!!!). Here is my favourite workaround, the advantage is that you do not need any extra packages. Points3d(x=1.2,y=c(.9,1,1.1),z=1.1, col=as.numeric(as.First of all: it is very unfortunate and surprising that R cannot draw error bars "out of the box". For this, we simply need to apply the text command several times: plot (1:10) Basic plot in R text ( x 3, y 4, First text 'This is my first text') text ( x 5, y 7, Second text 'This is my second text') The output of the. In Example 3, I’ll show how to add multiple texts to our plot. With the new data this is in response to the request for text and points: scatter3d(x=loadings], y=loadings], z=loadings], Example 3: Draw Multiple Text Elements to Plot. You offered no code to construct a "legend", so I played around with the example offered in rgl::text3d: text3d(1+ font/8, 1+cex/4, 1+famnum/8, text=paste(family, font), adj = 0.5,Ĭolor="blue", family=family, font=font, cex=cex) The scatter3d function does depend on rgl functions but has quite a few customization options. That's not a plot3d image (unless perhaps you have another package loaded), but looks like a scatter3d rendering constructed with the scatter3d function from the car package by John Fox: require(rgl) The plot with labels according to classes: l = as.numeric(as.factor(loadings)), size = 10, type = 's') Is it any possibility to add legend within rgl or maybe some independent legend can be attached to the plot?Īnswer is: scatter3d(x=loadings], y=loadings], z=loadings], Obtained plot has the same style, but is much simpler as there are only two levels of variable "Class": 'global' and 'local' l = as.numeric(as.factor(loadings)), size = 10) Scatter3d(x=loadings], y=loadings], z=loadings], The example data is given in a table: > loadings The 3D dimensional scatterplot is for resulting loadings from plsr analysis. What I would like to do is to build 3D scatterplot with color coding according to some factor variable. Manually specifying labels fig2 <-plotly (data iris, x Sepal.Length, y Sepal.Width, color Species, type 'scatter', mode 'markers') > layout (title 'Manually Specified Labels', plotbgcolor 'e5ecf6', xaxis list (title 'Sepal Length (cm)'), yaxis list (title 'Sepal Width (cm)'), legend list (title list (text.One of the possible packages for interactive 3D plots is rgl.
