Hi
I have probably a very simple question but I'm going crazy trying to find the solution. I have two data.frames with headers and I'm doing an intersection between them by names, such that the intersected data.frames are returned by: df1[intersect(names (df1), names(df2))] and the same for df2 Now, I want to have all the opposite data that did not intersect. I tried to do: df1[-intersect(names (df1), names(df2))] and some other stuff but it didn't work. Any ideas? Thanks, S.B.
