Dear R People:

I am trying to replicate a cool example that I saw on the R-bloggers some
time ago by kafka399.

Here are the lines tI think may be  causing the trouble:

gray_file <- read.pnm(path)

pos[i,] <- c(gray_file@grey)

The warning error that I get is
"In rep(cellres, length=2): x is NULL so the result will be NULL

Any suggestions would be much appreciated.

Thanks,
Sincerely,
Erin
