Is this a rhetorical question ? what could be simpler than
deparse(substitute(y)) when setting up the colnames ? If it's not
working for you for some reason then post your function. Or am I
missing something with the definition of "simple" ?
Or should I just use the 4-argument method?
You could, but even more efficient (and better control):
f <- function(x,y,rn=deparse(substitute(x)),cn=deparse(substitute(y))){
cat(rn,'=',x,'\t',cn,'=',y,'\n') }
> f(5,7)
5 = 5 7 = 7
> g <- 5 ; gs <- 7
> f(g,gs)
g = 5 gs = 7
> f(g,gs,'g','gs2')
g = 5 gs2 = 7
