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! 2009/5/19 Jim Lemon <j...@bitwrit.com.au>: > Katharina May wrote: >> >> Hi, >> >> how can I remove all empty objects (which are NA or have zero rows) >> from my workspace? >> >> > > Hi Katharina, > To remove objects that are all NA: > > for(object in objects()) if(all(is.na(get(object)))) rm(list=object) > > If by "zero rows" you mean objects that do not have a dimension: > > for(object in objects()) if(is.null(dim(get(object)))) rm(list=object) > > Jim > > -- Time flies like an arrow, fruit flies like bananas. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
