rename problems

[bachlaw]

It may just be me, but I continue to have problems "rename" in dplyr, even in version 0.4.3. You can replicate the problem here:

a <- c(1, 2, 3)
b <- c(10, 20, 30)
c <- data.frame(a,b)
c

This worked fine. Then:

rename(c, z=a)
Error in rename(c, z = a) : unused argument (z = a)

I tried the reverse as well:

This gives an error:
Error in rename(c, a = z) : unused argument (a = z)

I've looked for "dumb" moves on my part creating this issue, but I can't find any.

Try in a fresh R session - looks like you have something overriding rename

I had the same issue and it did not go away despite restarting the session. I loaded tidyr, dply, and plyr in my session. So that was causing the issue. I found the answer in this post on stack overflow.It resolved my issue.

might have a conflict with another package, did you try "dplyr::rename"?
