I suggest you spend a bit of time with an R tutorial or two and, in
particular learn about "logical indexing," as this basic R construct
seems to be mysterious to you.
Hi Bert,
especially the "match" help area is a little bit confusing.
And additional using a couple of programming languages with different
logical operators and different syntax is misleading me sometimes to the
wrong direction...
So the logic operations itself are not mysterious ;-) but the
translation to R.
And thank's a lot to give me the keyword to find for what I am was
looking for: logical indexing.
I can not count the sites where I was looking to solve my problem ..
with the wrong keywords ... :-)
Kind Regards Knut
