Subject: remove empty objects from workspace
In-Reply-To: <4A1296FB.3000700@bitwrit.com.au>
Thanks Jim, the removal of objects which are NA works perfectly!
For my second problem it didn't express myself correctly:
I actually meant objects with rows (attributes?) but no data in it
but I solved this
adjusting your approach:
for(object in objects()) if(is.null(dim(get(object))[1]) ||
dim((get(object)))[1] == 0) rm(list=object)
Thanks a lot!
