Re: [R] if-else that returns vector

?ifelse 'ifelse' returns a value with the same shape as 'test' which is filled with elements selected from either 'yes' or 'no' depending on whether the element of 'test' is 'TRUE' or 'FALSE'. This is actually rather startling, because elsewhere in the S (R) language, operands are normal

Re: [R] Problem with compatible library versions

The purpose of 'groundhog' is to support reproducible research. As Uwe Ligges pointed out, there are practical limits to that. Since I am typing this on a 10-year-old machine, it's clearly feasible in *some* instances, but as an illustration of Uwe's point, Ubuntu still supports 32-bit applications

Re: [R] if-else that returns vector

What a strange question... ifelse returns a vector (all data in R is vectors... some have length 1, but length zero is also possible, as are longer vectors) that is exactly as long as the logical vector that you give it, filled with elements from the respective positions in the vectors supplied

Re: [R] Linear discriminant analysis

It's possible that neither of these will help, but (1) you can look at the source code of the predict method (MASS:::predict.lda) (2) you can look at the source reference ("Modern Applied Statistics in S", Venables and Ripley) to see if it gives more information (although it might not); th
