not sure why it doesn't work, but try the following:
first, plot to a regular window, then run:
> dev.copy(device=png, file="yourfilename.png")
> dev.off()
see if that produces a file you want.
another note: what do you mean you can't just "copy and paste the graph"
in ubuntu? doesn't pressing print-screen make a screenshot? doesn't
pressing alt-printscreen make a screenshot of the current active window?
(or even from the main menu, "applications-> accessories -> take
screenshot" should work).

I have trying to figure this out all day so hopefully the answer isn't too
obvious. I am able to view a graph in the viewer window. However, I need to
export graph outside of the viewer window. Here is the script I am using:
png("Compare.png")
plot(compare$DepthSLI, compare$DischargeSLI, col="blue", xlab = "Average
Water Depth (cm)", ylab = "Discharge (m^3/s)", xlim=c(5,40),
ylim=c(0.03,0.1), main="Discharge in Flume 1")
dev.off()
null device
1
When I do this R simply produces an empty file that produces an error
message when I try to open it. I have tried this same script with every file
format available under help(device) all with the same result. I am running
Ubuntu 8.04 so I unable to simply copy and paste the graph as in windows. I
am fairly sure I have all the right packages installed. I am running R
2.6.2-2. Any suggestions?
