Why I am not able to load library(R.matlab)? Other packages are fine.
For some unknown reason, you've managed to install R.matlab without the dependency R.methodsS3 (cf. http://cran.r-project.org/web/packages/R.matlab/) or it happened due to some other glitch somewhere. Try to reinstall R.matlab. If that doesn't help, explicitly install R.methodsS3 and retry. If you get the same error with the other dependencies (R.oo and R.utils), do the same. /Henrik

Dear R list, I am trying to do use the R.matlab library, I did the following, but it does not work.

Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) : there is no package called ?R.methodsS3? Error: package or namespace load failed for ?R.matlab? This is my session info.

My R is up-to-date, R 3.2.0. Why is this happening? Is it because I
installed the new R version, instead of updating it? Maybe things are in a
different directory?
Thanks so much,
Mike
