[R] Is a .R script file name available inside the script?

[Darren Weber]

Hi,

if we have a file called Rscript.R that contains the following, for example:

x <- 1:100
outfile = "Rscript.Rout"
sink(outfile)
print(x)

and then we run

>> source("Rscript.R")

we get an output file called Rscript.Rout - great!

Is there an internal variable, something like .Platform, that holds
the script name when it is being executed?  I would like to use that
variable to define the output file name.

Best, Darren
