Dear R wizards: I just got stung by the ifelse() feature.
> a <- 10:15 > b <- 20:300 > test <- 1 > ifelse(test,a,b) [1] 10 I had not realized that this was the default behavior---I had expected 10:15. mea culpa. however, I wonder whether it would make sense to replace ifelse with a different semantic, where if test is a single scalar, it means what a stupid user like me would imagine. Aside, I like the flexibility of R, but I am not thrilled by all the recycling rules. I either mean I want a scalar or a vector of equal/appropriate dimension. I never want a recycle of a smaller vector. (I do often use a recycle of a scalar.) regards, /iaw ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
