R help - Apr 2013 - Importing from file to graphic window

Dear all,

Can I "import" the content of a pdf (or jpg) and put it in the graphic
window?.

Thanks.

jpeg: not in base R, but you could look at the CRAN jpeg package which says it
reads and writes jpegs.

PDF: Not in base R. But you can create a PDF with a known filename and then open
it in the default PDF viewer using shell() if the OS supports file associations.
In Windows XP (I'm at work) with Adobe X installed, and with R 2.15.3, the
following works

pdf(file="temp.pdf")
hist(rnorm(500), breaks=15, col=rainbow(25))
dev.off()
shell("temp.pdf")

If shell doesn't work, consider, for example, openPDF from the Biobase
package

And you could use any search engine to search for "display jpeg in R"
or "display PDF from R" or "import image into R" and so on.
