R freezes when loading the package 'clusterSim' with OS x El Capitan

Question

When I try to load the package clusterSim, R freezes without any output. I'm new to R and I don't know how to deal with this issue. I did not find any help in forums or other documentation.

SessionInfo() in R provides the following output:

> sessionInfo()
R version 3.2.4 (2016-03-10)
Platform: x86_64-apple-darwin13.4.0 (64-bit)
Running under: OS X 10.11.3 (El Capitan)

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 

I've tried this in the following ways always with the same outcome:

• From the R console with the package installer and from the command line.
• From the Terminal
• From R-Studio with the GUI and the Console.

I've tried as well to remove and reinstall R, R-Studio, The package 'clusterSim' and it's dependencies 'cluster' and 'MASS'.

When trying to install the package 'clusterSim' from source, the following output is generated, before the it freezes:

> install.packages('clusterSim', type='source')

Can anyone help me to get this package loaded? It might be already useful if I knew how to get some more output when executing the command to load the package.

Thanks,

A classmate found a solution:

Install https://www.xquartz.org and then restart R and then R does not freeze when you load clustermsim.

give it a go, it does work.
