Reassembling logical operations on boolean vectors in Gnu R
What a headline.. It’s about combining boolean vectors in R.
I just had some problems with computing a boolean vector as a result of applying
AND to two boolean vectors:
As you can see, it’s a nice result, but not what I want.. My hack was the following:
When Rumpel, my personal R-freak, saw that hack, he just laughed and told me the short version of this hack:
Nice, isn’t it ;)

The Rumpel solution is like the syntax in other languages. && is the bitwise operator und & ist the logical operator. The behavior with vectors is specific for the languages. I think matlab has a similar syntax. You need more languages in your head. I need a bag with english knowledge :P
Michael is perfectly right, it’s just the other way round (&& is the logical “and”, & the bitwise).
Thanks to both of you, sometimes I miss the wood for the trees (-;
