Your code above opens 2 devices (1=postscript, 2=x11) and only writes to
the second. Thus nothing is ever written to nor do you ever close the
first device. I think what you want is:
postscript(file = "C:/Temp/Fig1.eps", height=4.0, width=4.0,
horizontal = FALSE, onefile = FALSE, paper = "special")
x <- c(10,20,30)
y <- c(5, 7, 9)
The fact that you never closed the first device explains why you
couldn't view it outside of R.
