[Rd] Ellipsis to Two Functions When One Has Nested Functions

If I have a function

aFunction <- function(data, alpha, ...)
    transform(alpha, ...)
    rowMeans(data) > alpha

f <- function(data, selection, ...)
    selected <- selection(data, ...)
    plot(data[selected, ], ...)

f(aDataset, aFunction, alpha = 10, pch = 19, transform = sqrt)

and selection calls another function, which has ... and that function calls other functions, is there an easier way than getting the formals of all the functions called internally by selection, and all of the formals of functions called by plot ? Is there any option to change the error into a warning message ?
