1) What operating system are you using? Linux 2) What error message was displayed? package 'multicore' is not available (for R version 2.15.2) 3) What was the exact command you used that resulted in the error? install.packages(c('multicore','doMC','foreach','quantreg','R.utils')) 4) Please copy and paste any additional screen output that resulted from running the command Package ‘multicore’ was removed from the CRAN repository.

Formerly available versions can be obtained from the archive.

Consider using package ‘parallel’ instead.

If the authors don't maintain zinba and port it to the newest R, your only option is to install R 2.15.0. You should be able to compile it and run it side-by-side with your newest R.

I installed multicore in 2.15.0 with no problems.

Please use the attached version. This uses doParallel for multicore processing instead of the multicore package.

install.packages(c("R.utils", "quantreg","doParallel","doMC","foreach"))

Hi! Maybe it would be worth adding this version (2.03.1) to the list of releases? It would make it easier for people to immediately find and download the right version (R versions >3.0 are very common nowadays).

Best, André
