[R] can Rgui.exe be launched with a script as an argument?

[Bill Bachman]

Thank you to Paul Murrell for a solution:

# test.R
require(graphics)
a<-c(1,2,3,4)
b<-c(1,4,9,16)
plot(a,b)

I assume this is windoze. Have you considered using the Rterm? You can have
in your script the plot to be created as an eps file
