I have encountered a problem with merge() that appears to be a bug.
Here's an example to illustrate it.
> tmp1 <- data.frame(a=letters[1:3],b=LETTERS[2:4],x=1:3)
> tmpa <- expand.grid(a=letters[1:4],b=LETTERS[1:4])
> tmpm.1 <- merge(tmpa,tmp1)
> tmpm.2 <- merge(tmp1,tmpa)
Error in "names<-.default"(*tmp*, value = vnames) :
names attribute must be the same length as the vector
I'm using R 1.3.0, and it occurs on both the Macintosh and Solaris versions.

(I've searched various places, including a list of fixes for v1.3.1,
the faq, 2001 r-help archives, and haven't found anything about it)
Thanks
