Power BI, R

Stacia Varga troubleshoots an issue integrating Power BI with R:

As I was putting together an example of using an R script as a Power BI data source, I ran into some issues on my development machine that was frankly driving me crazy. When I tried to run the query in Power BI with my R script (that ran successfully in the IDE, by the way), I kept getting this message:

DataSource.Error: ADO.NET: R script error.
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
  namespace 'scales' 0.3.0 is being loaded, but >= 0.4.1 is required
Error: package or namespace load failed for 'rnoaa'
Execution halted

Stacia’s answer works as long as the .libPaths() results match expectations.  Another idea would be to set the R_LIBS_USER user-level environment variable to the desired starting directory and that should force the directory in the environment variable to be first when calling .libPaths().
