You need to get() their elements instead of merely using variable names.

"union" handles two vectors' elements to get their union, but I have many vectors and I want to get the union of all of them. So I wrote a loop: all <-c(); for(var in ls(pattern="xyz")) # all of the vectors with pattern of "xyz" { all <- union(all, var); } but the result is like this: ("xyzblabla1", "xyzblabla2", "abcxyz", ... ) -- just a collection of the variable names, not the union of their elements. How can I solve this problem? thanks!
