I often find myself trying to get a quick assessment of how much of one vector
is inside of another vector. I almost always try this with variables that are
some sort of identifier, like a client id number or an SSN. I typically do this:
table( DF1$Identifier %in% DF2$Identifier)
This will return a count of True and False logical responses. However,
sometimes when I try to do this my computer will freeze and I am unable to stop
or escape the process, requiring me to shutdown R via the task manager. I was
wondering if anybody else experiences this and, if so, why this might be
happening.
Thanks in advance,
Joel
