I'm trying to determine what's changed from my customized [defunct] Panther setup to the basic Tiger one I am using now. $ open /Applications/Utilities/X11.app $ open /Applications/R.app
capabilities("png") # TRUE
x11()
plot(rnorm(10), main="test")
dev.copy(device=x11) # so far so good
dev.print(device=png, file="test.png")
Error in dev.copy(device = function (filename = "Rplot%03d.png", width = 480, : invalid graphics state Get same result when using "quartz" device. I'm sure my previous environment had /usr/local/lib/libpng but I'm trying to keep this machine a little closer to stock, attempting to use only what typical non-developer useR would have loaded. Is this missing libary causing the problem?
