'objects()' returns character strings - the names of objects - then
the dim of the character strings are all NULL.
I'll assume that's what you are getting at - you've not posted an
example or the output you are getting or why it 'does not work'.
Maybe you want this:
> sapply(objects(),function(x){dim(get(x))})
$f
NULL
$m
[1] 2 5
$x
NULL
$y
[1] 5 2
- where m and y are matrices, f is a function, x is a scalar.
