When you start using R, it can be confusing that if you assign something to an object you do not get visual feedback: x x [1] 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 You can exploit this fact for doing a quick-and-dirty lottery. Assume you have a [...]
I don’t know the first thing about programming, but sometimes you see something and appreciate how elegant it is. This small solution from r-help is a good example. Someone wanted, given a vector c(‘p’,'p’,'t’,'t’,'t’,'p’,'k’,'t’) to produce NA NA 1 2 3 test
This question was on the R-help mailing list today: I have a data frame “test”: test test$total [1] 7 7 8 8 9 9 10 10 to this: > rep(needed,length.out=length(test$total)) [1] 7 9 7 9 7 9 7 9 The two vectors just happen to coincide at test$total[1] and test$total[6]. The recycling is of course [...]
