Accessing the formals() of a non-exported method without :::?
Thanks Michael, somewhat embarrassingly, I had forgotten that a package can refer to any of *its own packages*. So I don't need analogue:::foo.bar as that is being called from a function in the analogue namespace. Cheers, G On 23 August 2013 09:27, R. Michael Weylandt

Dear List, I'm in the process of making tweaks to my various R packages following changes in r-devel for package checks. I'm wondering about the one use of ::: in one of my packages. I am arranging for a call to a non-exported S3 method via do.call. For this I need the arguments of the function and hence I was doing Args <- head(formals(analogue:::wa.default), -1) Following the recent thread on legitimate uses of ::: I think the above is both acceptable and won't generate a Note now with R CMD check following a recent change to that code. But is there a better way to get the formal arguments of a non-exported S3 method?
Something like (untested) formalsS3 <- function(...) formals(getS3method(...)) might work. I haven't checked to see how R CMD check feels about getS3method() though. Michael
