Merge multiple data frames - Error in match.names(clabs, names(xi)) : names do not match previous names

Question

I\'m getting some really bizarre stuff while trying to merge multiple data frames. Help!

I need to merge a bunch of data frames by the columns \'RID\' and \'VISCODE\

Answer 1

Not sure I can help unfortunately but thought I would post as I found this searching for help on this error. What I effectively had was:

a <- cbind(b,c)
d <- merge(a,e)

And I got that same error. Using a <- data.frame(b,c) fixed the problem, but I can't work out why.

object.size(a);1248124200 bytes

object.size(c);1248124032 bytes

So something is different. All classes are the same, str() reveals nothing. I'm stumped.

Hopefully that aids someone else in the know.
