You can also just pass the ... to the next function. E.g., the following two functions do the same thing:
> myPaste1 <- function(...) paste(...) > myPaste2 <- function(...) do.call(paste, list(...)) > myPaste1(1,2:3,4) [1] "1 2 4" "1 3 4" > myPaste2(1,2:3,4) [1] "1 2 4" "1 3 4" Bill Dunlap Spotfire, TIBCO Software wdunlap tibco.com > -----Original Message----- > From: r-help-boun...@r-project.org [mailto:r-help-boun...@r-project.org] On > Behalf > Of Steve Lianoglou > Sent: Tuesday, May 15, 2012 10:49 AM > To: Ben quant > Cc: r-help@r-project.org > Subject: Re: [R] pass objects into "..."
