Hi,
Say I have
function(aa,bb,cc) { does something }
and I want to go through all (or a subset) of function arguments to check if
they're missing. Of course, I can check each one in turn, ie.
if (missing(aa)) {}
if (missing(bb)) {}, etc.
But is there a construct like the following to go through all of them and
perform some default action? Like this (which doesn't work obviously):
for el in c('aa','bb','cc')
if missing(el) {do something}
I was thinking could to eval(parse( <construct string here> )), but was
hoping there was something cleaner.
Thanks
