I just tried it and you are right -- wget works. So this does it:
my.source <- function(url) {
on.exit(unlink(tmp))
tmp <- tempfile()
download.file(url, dest = tmp, method = "wget")
source(tmp)
}
stripchart.url <-
"https://svn.r-project.org/R/trunk/src/library/graphics/R/stripchart.R";
my.source(stripchart.url)
Maybe source could be modified to have a method= argument so that this could be
done without a custom source function?
