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?
