Error: Maximal number of DLLs reached

Question

I\'m writing an R package which depends upon many other packages. When I load too many packages into the session I frequently got this error:

Error in dyn.lo         


        

Answer 1

As of R 3.4, you can set a different max number of DLLs using and environmental variable R_MAX_NUM_DLLS. From the release notes:

The maximum number of DLLs that can be loaded into R e.g. via dyn.load() can now be increased by setting the environment variable R_MAX_NUM_DLLS before starting R.
