Please consider renaming this package

[m-stanley]

There is already a package on CRAN called RGA:

https://cran.r-project.org/package=RGA

Having one called rga is therefore unlikely to be accepted, and even if it was it would be incredibly confusing!

In fact I think it's already confusing since if you google "rga package" this one is listed first, but this isn't the CRAN one.

As I recall, this rga was available and known to the Google Analytics and R communities before the other RGA package. This might go so far as to explain the Google ranking.

Possibly, but this package was beaten to CRAN, so this one is unlikely to be accepted now with this name. Hence my recommendation to change it.
