You can use paste() within a loop to construct the name of the resultant
ps files. An example:
number.graphics <- 5
for(i in 1:number.graphics)
postscript(file = paste("C:/Rfigures/plot_", i, ".ps", sep = ""))
The above will create 5 ps files called plot_1.ps through plot_5.ps in
the defined directory.
See ?paste for additional information.
