You did invite trouble by creating and subsequently a function that _has_ no source representation though: > fjj <- function() x > formals(fjj) <- list(x=quote(c(a=2, b=4))) > fjj() a b 2 4 > fix(fjj) > fjj() a b 2 4 > fjj function (x = c(a = 2, b = 4)) x -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.
