if (!is.na(taa))

if (!is.na(gaa))
extra <- paste(extra, " -dGraphicsAlphaBits=", gaa, sep = "")
cmd <- paste(shQuote(gsexe), " -dNOPAUSE -dBATCH -q -sDEVICE=",

one way to solve bad looking density plots in postscript
...are exported to postscript(
a=matrix(1:100,10,10);image(a,col=rainbow(100);dev.copy2eps(file="image.eps")
)
The result often looks bad when rendered on screen. The help page states that this is because programs use anti-aliasing. That seems to be true - turning off anti-aliasing for gs (-dGraphicsAlphaBits=1) of in OSX's preview makes the plots look really smooth, but makes everything else look bad (personal opinion..). The plots do look ok in acrobat reader. I think it would be much better if R corrected this problem - even if it is not totally R's fault.
It seems that using the option useRa...
