Error in library(surv2sample) : ?surv2sample? is not a valid installed package Furthermore, if I go through "Packages->Load package" from the top bar surv2sample isn't in the list. It is, however in the directory that the library() function uses and its contents look similar to the other, working packages. One odd thing is that I had to download the package .zip and install locally since it doesn't show up in the GUI package list even with all repositories selected. I can't imagine why it won't load given that everything else seems to work properly. Any ideas?
That package has been archived (http://cran.r-project.org/src/contrib/Archive/surv2sample/). Only a source .tar.gz is available. AFAICS it needs to be modified to work with R >= 3.0.0. As it is now it can't be installed and doesn't pass R CMD check. It needs to be fixed. You could try to contact the original author. Berend
