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 On Thu, May 28, 2015 at 11:47 AM, C W <tmrs...@gmail.com> wrote: > Dear R list, > > I am trying to do use the R.matlab library, I did the following, but it > does not work. > >> library(R.matlab) > 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. > >> sessionInfo() > R version 3.2.0 (2015-04-16) > Platform: x86_64-apple-darwin13.4.0 (64-bit) > Running under: OS X 10.10.3 (Yosemite) > > locale: > [1] en_US.UTF-8/en_US.UTF-8/en_US.UTF-8/C/en_US.UTF-8/en_US.UTF-8 > > attached base packages: > [1] stats graphics grDevices utils datasets methods base > > My R is up-to-date, R 3.2.0.
