R editor freezes after running a script

Hello.

I am running R (3.3.1) with R Commander (2.3-0) and XQuartz (2.7.9) on an iMac (late 2012) with Sierra. RAM is 32 GB. The file I am working with has about 350,000 records and 200 variables.

After running a script from the R console (using either the GLM or epiR libraries) the editor freezes when I try to open a new script, and I get the spinning beach ball. When the editor freezes, I still have at least 20 GB of free RAM. The only way out is to force quit R.

The epiR script repeats a series of calculations for a group of about 30 2 x 2 tables (epi2by2). The GLIM script runs Poisson regression with robust variance estimation. Both scripts run smoothly.

I do see this behavior when running R from RStudio (0.99.903) plus R Commander and using the RStudio console to run the scripts.

The issue does not disappear when I reinstall R. 

Thanks.

Jos?
