Thank you for your help so far. I deleted the OsGeo4w folder and did a fresh express install with QGIS, GDAL, and GRASS checked. This fixed the "Error in py_run_string_impl(code,...

ERROR 4: Unable to open EPSG support file gcs.csv. Try setting the GDAL_DATA environment variable to point to the directory containing EPSG csv files.

Additionally, the error seems to break rgdal's functionality as well as limiting qgis operations to data with coordinates in terms of unprojected WGS84 coordinates. ``` library(rgdal) head(rgdal::make_EPSG()) # code note...
