[R] getting source file name

[Ott Toomet]

Hi,

I have not tried to get a call when source'ing a file, but you get current
function call from inside of the function using

sys.call().

When I want to get the name of the variable which is the first argument of a
function (e.g. for a plot title), I use

varname <- unlist(strsplit(as.character(sys.call()), "[(,)]")[2])

Perhaps you find a solution, playing around a bit.

Best wishes,

Ott
