Hi all,
Is there a way to modify the optional arguments (...) passed to a
function, so that these can be passed in modified form to a subsequent
function call? I checked "Programming with Data" but could not find a
solution there.
What I'd like is something along these lines:
test <- function(x,y,...) {
if(!hasArg(xlab)) { ___add xlab to ...___ }
if(hasArg(xlab)) { ___remove xlab from ...___ } # alternative
plot(x,y,...)
}
Of course, I could use separate calls, like
if(hasArg(xlab)) plot(x,y,...) else plot(x,y,xlab="label",...)
but this gets complicated if there is more than one such case to consider.
Thanks
Pascal
