[R] PDF Corrupted?

[rkevin...@charter.net]

I am running R 2.9.2 and creating a PDF that I am trying to open with Adobe Reader 9.2 but when I try to open it the reader responds with

"There was an error opening this document. The file is damaged and cannot be repaired.:

I am using the R command(s):

pdf(file="cat.pdf", title="Historical Sales By Category")
for(j in 1:length(master))
{
d <- as.Date(master[[j]]$Period[1], format="%m/%d/%Y")
fit <- ets(ts(master[[j]]$Quantity, start=c(1900 + as.POSIXlt(d)$year, 1 + as.POSIXlt(d)$mon), frequency=12))
plot(fit, col.axis = "sky blue", col.lab = "thistle")
title(master[[j]]$Category,
cex.main = 2, font.main= 4, col.main= "blue")
}

Any idea what I am doing wrong?

Thank you.

Kevin

You are not closing the PDF file with dev.off() when you are done
plotting...

HTH,

Looks like you need to do dev.off() after the plot to properly close the
file.

Hi Kevin,

Close the device once the plot is completed:

pdf(...)
plots go here
dev.off()

HTH,
Jorge

Try doing dev.off() after you finish the plot. That will close the
device and should make it available for viewing.

Cheers,

Simon.

try dev.off() at the end. Yous is an FAQ.
