Only for the record, an unnecessary overhead when nothing is assigned:
x <- integer(10) str(x)
int [1:10] 0 0 0 0 0 0 0 0 0 0
x[c()] <- 1.0; str(x)
num [1:10] 0 0 0 0 0 0 0 0 0 0 'x' could equally well have renamed untouched. /Henrik
x[c()] <- value sets the mode to mode(value)

I disagree. I think the language is more predictable, hence easier to use, if the class of the output of a function depends only on the classes of the inputs, not on the classes and lengths of the inputs. Bill Dunlap Spotfire, TIBCO Software wdunlap tibco.com
