Max DLL issue revisited

[mjdufort]

I'm attempting to install powsimR on a Mac, and hitting the DLL limit even after setting it to the maximum number possible (153).

Here's the error message:

Error in dyn.load(file, DLLpath = DLLpath, ...) :
unable to load shared object '/Library/Frameworks/R.framework/Versions/3.4/Resources/library/nloptr/libs/nloptr.so':
`maximal number of DLLs reached...
ERROR: lazy loading failed for package ‘powsimR’

• removing ‘/Library/Frameworks/R.framework/Versions/3.4/Resources/library/powsimR’
  Installation failed: Command failed (1)

And here's the sessionInfo() output:

Hello,

starting with the new version I included an additional number of R packages for imputation and normalisation. Therefore I have changed the recommendations (see "DLLs and ulimit" in the README):

I recommend to increase the maximum number of DLLs that can be loaded to at least 500.
In addition, the user limits for open files (unix: ulimit) might have to be set to a higher number to accomodate the increase in DLLs. Please check out this help page for MACs: https://gist.github.com/tombigel/d503800a282fcadbee14b537735d202c.

Kind regards
Beate
