The OP's question might be interpreted as "draw the R logo in R",
meaning base R graphics. This interpretation excludes packages like
rsvg that use a rendering engine such as
https://wiki.gnome.org/Projects/LibRsvg (the R here is for
"Resplendent SVG", not the R language).

Hi Witold,
See also this thread on R-pkg-devel. Quoting Duncan Murdoch, "That
looks like a bug in grDevices."

Hi,
There are many occurrences of the CIK number in the page source. This pulls
out the first node containing it:
node <- getNodeSet(doc[[1]], "//link[@rel='alternate']" )
>From there you can extract the number. Here's one way to do it.
strsplit(strsplit(unlist(node)[[5]], "CIK=")[[1]][2], "&ty
you might also try (names modified a bit since R already has a NULL object)

Hi Matt,
I assume that you want a tabular text file of the results. Since I
don't know what your tempA and tempB are I'll steal some examples from
?t.test

Now looking at ?dump, the first argument needs to be *ch
Here's an attempt using sapply:
