Greetings, all.
I'm fiddling with some text manipulation in R, and I've found
something which feels counterintuitive to my PERL-trained senses; I'm
hoping that I can glean new R intuition about the situation.
Here's an example, as concise as I could make it.
trg-c(this,that)
# these two
If you are using grep then I think you have it right. Note that
this %in% trg
is also available.
