Title Body

I often prefer to use a light text on dark background colortheme in IDEs. When I plot something in R the default colorscheme for plots is black text/borders/points on white background. I was trying to change this by default, preferably for specific devices called from R by default ( X11cairo , RStudioGD ), while keeping the normal defaults for 'output' devices such as pdf and png . My question is twofold: (1) How can I set default graphical parameters? and (2) Can I do this only for particular devices? For example, I can easilly set the colorscheme in the current device with par : par( bg = "black", col = "white", col.axis = "white", col.lab = "white", col.main = "white", col.sub = "white") plot(1) Creates the white on black plot as expected, and as expected resetting the device returns to defaults: dev.off() plot(1) I tried putting the following in my .Rprofile : graphics:::par( bg = "black", col = "white", col.axis = "white", col.lab = "white", col.main = "white", col.sub = "white") graphics:::plot(1,type="n",xlab="",ylab="",axes=FALSE) graphics:::text(1,1,"Plotting area") Which works somewhat, except that it opens a plot window on startup which can be abit annoying and in RStudio it doesn't open the RStudio device but an x11 window. Also if I close that window the parameters reset again. I would prefer to be able to have this "colorscheme" used by default every time I open a plotting window with in for example RStudio's default device.
