I have a new installation of R and R studio: each time i try and test the graphics I get the following type of error. I cannot find any information that helps me to understand how to fix this device error.

plot(cars) Error in RStudioGD() :
Shadow graphics device error: r error 4 (R code execution error) demo(graphics)

demo(graphics)
---- ~~~~~~~~

Type to start :

require(datasets)

require(grDevices); require(graphics)

Here is some code which illustrates some of the differences between

R and S graphics capabilities. Note that colors are generally specified

by a character string name (taken from the X11 rgb.txt file) and that line

textures are given similarly. The parameter "bg" sets the background

parameter for the plot and there is also an "fg" parameter which sets

the foreground color.

x <- stats::rnorm(50)

opar <- par(bg = "white") Error in RStudioGD() :
Shadow graphics device error: r error 4 (R code execution error)

   Steven,

   The RStudio graphics device is just using R to create a png file. Can you try opening the png device and saving a plot? Here is an example to try:

   > png()
   > plot(cars)
   > dev.off()
   

   This will save a plot to the current working directory. Can you see if that works?
