colSds does not work since the last matrixstats update in R

2018-06-27 15:30:36

It seems like the colSds is not working since the last update in matrixStats (v0.10.0, 2014-06-07). It worked for me before, but now it returns an error message:

Error: no applicable method for 'colCounts' applied to an object of class "data.frame"

Here is an example:

library(matrixStats)
data(mtcars)
colSds(mtcars)

I use R version 3.1.0 (2014-04-10) on windows 7(x64). Platform: x86_64-w64-mingw32/x64 (64-bit). Does anyone have a clue what went wrong, and what can I do with it?

Thanks, Tamas

It looks like colSds only works on matrices. This works for me.

colSds(as.matrix(mtcars))
