Assuming I would go into the trouble of messing with the existing R
scripts that create mentioned postscripts/pdfs, how can I achieve that
an array of scripts append to a single ps/pdf? I would want the first
script to create the file if it does not yet exist and all other to
append to it with new pages. I tried this simple example:
#first.R
pdfFileName <- paste("C:/testfile.pdf", sep="")
pdf(pdfFileName, onefile=TRUE)
plot(c(1,2,3))
abline(v = 2)
dev.off()
#second.R
pdfFileName <- paste("C:/testfile.pdf", sep="")
pdf(pdfFileName, onefile=TRUE)
plot(c(1,2,3))
abline(h = 2)
dev.off()
The second overwrites the first and I cannot accumulate across
different scripts. I can also not do it if I happen to start different
pdf file environments in the same script despite it sharing the same
file and having the 'onefile' set to true. Is it really just limited
to the a single environment?
