Dear Helmut,

» Using

» Good luck coding that with a loop and a nested

I think that's really what pissed me off. I thought something like if... else... would be very logical and easy. Maybe because these are real words from a language I can understand. But it looks like R and I are following different kinds of logics.

When you learn a new language and start speaking it with somebody, that person will usually show some goodwill, ignore grammatical mistakes and try and understand what you mean. R made no efforts of any kind, even though what I was trying to achieve was pretty obvious

» If you have a vector of data (say

Yeah, ElMaestro started using this kind of vocabulary too when we were exchanging email. That got me even more confused. All I learnt at school about vectors is the geometric side of the concept - what Wikipedia apparently calls Euclidian vector. I had some problems understanding what an arrow between two points had to do with what I was trying to achieve.

Sorry ElMaestro, we're going quite far from your original question...

» Using

`if()`

, its relatives, and loop-constructs (`for(), while(), repeat()`

) in many cases are prone to errors» Good luck coding that with a loop and a nested

`if() { do this } else { do that } elseif { oops }`
