Saving graphics as postscript files

• in R
  1. >postscript(file="file.eps",horiz=TRUE,onefile=FALSE,width=8.5,height=11,paper="letter")
     - the 'onefile' part makes an eps file rather than a ps; use 'onefile=TRUE' to get regular ps; eps is good for embedding in Latex files
  2. R graphics commands.....
  3. >dev.off() #this kills of the device and closes the postscript file - I have had printing problems if I don't do this
• a second way in R
  1. R graphics commands ...
  2. dev.copy2eps(file="file.eps",width=4) # note that if you specify both width and height, the aspect ratio may not be preserved
• in S:
  1. S graphics commands ....
  2. >printgraph(file="file.ps",print=F,maximize=TRUE,horizontal=FALSE,width=8.5,height=11)
