Still trying to get into the R logic... what is the "best" way to unpack (on LHS) the results from a function returning multiple values?
I can't do this apparently:
R> functionReturningTwoValues <- function() { return(c(1, 2)) }R> functionReturningTwoValues()[1] 1 2R> a, b <- functionReturningTwoValues()Error: unexpected ',' in "a,"R> c(a, b) <- functionReturningTwoValues()Error in c(a, b) <- functionReturningTwoValues() : object 'a' not foundmust I really do the following?
R> r <- functionReturningTwoValues()R> a <- r[1]; b <- r[2]or would the R programmer write something more like this:
R> functionReturningTwoValues <- function() {return(list(first=1, second=2))}R> r <- functionReturningTwoValues()R> r$first[1] 1R> r$second[1] 2--- edited to answer Shane's questions ---
I don't really need giving names to the result value parts. I am applying one aggregate function to the first component and an other to the second component (min and max. if it was the same function for both components I would not need splitting them).
