How to speed up int2bin conversion?
..., ndigits-q+1] <- (x %% 2) x <- (x %/% 2) } bin<- apply(base,1,paste,collapse="") return(bin) } Since it is still slow, I have to find a way to express this more elegantly. I'd really appreciate any help. Thanking you, with best regards Jonas Jägermeyr Potsdam Institute for Climate Impact Research Research Domain II [[alternative HTML version deleted]]

Number with fixed digit length - zero fill-up
...rst digit which is zero disappears. So how can I set any number (e.g. x = 10110) to a 8-digit zero fill-up (x = 00010110) in order to address digit indices? Or other way round, how can I make the 'substr' function to count from the right hand side? Thank you.
