Question

I am exporting graph outputs from R to a pdf file.

I would like to add the Sys.time() and Sys.Date() to the outfile name.

For instance I have a statement

pdf("output filename.pdf", 8,10)

I would like to output to look like
output filename 2010-03-25 2pm.pdf

or something similar.

Answer 1

You could try

pdf (file=paste (Sys.time(), ".pdf", sep=""))
plot (rnorm (100))
dev.off()
