My script:
raw = read.table("c:\\Documents and Settings\\protein\\My Documents\\My
Fragments\\file1.txt", header = TRUE)
#Normal Average Signal VS Pool
jpeg("Normal Average Signal vs Pool_test.jpg", width = 800, height =
600)
xx_norm = raw[,3]
yy_norm = rowMeans(raw[,4:13])
plot(xx_norm, yy_norm)
dev.off()
I confirmed that the data base works and the plot function does work on its
own. But whenever I try running it and output to jpg, it gives me "null
device"
the whole script was working just earlier.
thanks for the help.
