Hello List,
I have many data frames in environment.? I need to keep 3 data frames only, con DB2 and ora.?
I write the script to do this.?
rm(ls(pattern != c("(con|DB2|ora)")))


but it give me an error message:


Error in rm(ls(pattern != c("(con|DB2|ora)"))) :?
? ... must contain names or character strings

I think the pattern option doesn't support != ? and is it possible to fix this?
Thank you,
Kai
