How can I check if a certain ... argument has been passed on to my
user-defined function or not?
foo <- function(data, ...)
### here I want to check whether xlab was passed with the ... arguments
### or if the ... arguments did not contain an xlab argument
I tried missing(xlab) , exists(xlab) and several other things but did not
find a solution.
