[R-sig-Geo] rgdal warning

[Panasci, Michael]

My question is in regards to the Implications of the "rgdal::checkCRSArgs:: no proj_defs.dat in PROJ.4 shared files" warning.
I recently solved this problem on a high-performance Linux cluster by redefining the PROJ_LIB path with:

export PROJ_LIB=/opt/ohpc/pub/libs/intel/proj/5.0.1/share/proj

I generated lots of data before finding this fix.  Despite receiving the warning message, does this actually lead to erroneous data?  All of my projection components were appropriately defined and the code seemed to have run fine (based on looking at the results).  Now that the issue is resolved and I no longer receive the warning, I'm wondering if I need to regenerate all the data from before realizing this fix.  I have not been able to find anything definitive on this message board regarding implications of that error.  Thoughts?
