[R-gui] Plots not generating or running in web-browser

Hi,
I am a beginner in R (using it for about 2-3 days now) and I have a couple
of problems I am encountering.
I am working on a windows machine and using putty to ssh into the "box"
where R is installed (I think Unix is running on the box I ssh into). The
problem I am facing is that when I try to plot using the plot function in R
(after invoking x11), nothing shows up - no window pops up with the plot.
But when I use the startx command in cygwin and ssh, the graph pops up.
My project is to graph a couple of points and display it on the web, so that
other users in my group can view it. The code I am using just to generate a
graph of random numbers is as follows:
#! /bin/sh /usr/bin/setR
cat("Content-type: text/html", '\n\n')
library(grDevices)
library(graphics)
cat("<html><head><title> 1st test page </title></head>",'\n')
cat("<body>",'\n')
r <- sample(1:20, 5)
cat("Random plot: ", r,'<br/>\n')
x11("192.9.200.232:0 <http://192.9.200.232:0>.0")
png(file="/tmp/R-web/random.png")
plot( r, type="b" )
dev.off()
cat("<img src='http://splustest/plots/random.png'/>",'\n')
cat("</body>",'\n')
q(save="no")
Now when I open a webbrowser on my machine and load this html/.R code, the
graph is not generated (as I checked in the random.png file) nor does it
show up. Clearly, this is happening because some x11 settings on my machine
is missing. I am stuck at a point where I do not know how to fix this
problem. I would be thankful for some helpful advice.
