Merge problem
...eas TransTable has 47296 rows. I
would expect when I merge the two data sets, with all.x=F, and
all.y=F, that the intersection would yield 8000 rows, considering
dat0 is a subset of TransTable.
However, I get a neat little surprise when I check the dimensions of
the resultant data frame - dat0merge, the merged data frame has 8007
rows! How can this be? Where did these extra 7 rows come from?
This appears to defy logic!
Thank you in advance for your help. I've put my code below for
reference.
