Team - I've been reading the book and want to work the solutions to gain a better feel for the capability. That said, I am struggling to install the package and have tried both from Github and CRAN. Here's the error I get:

Error: package or namespace load failed for ‘BasketballAnalyzeR’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/Library/Frameworks/R.framework/Versions/4.0/Resources/library/Rcpp/libs/Rcpp.so':

In addition: Warning message:

I'm using the R 3.6.3 version under Windows 10, and I'm with problems when installing some packages, especially those - gggplot2, c50 and now, ggthemes.

The standard warning is: Error: package or namespace load failed for ‘ggthemes’ in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]):
object 'vI' not found

I've also tried install those packages with dependencies = true, and directly from the cran.org website, also tried install in R console instead of RStudio, without success.

I'm thinking that the folder where the libraries are unzipped could be the problem. Does the folder where the libraries are installed makes some difference? I didn't change this settings when installing R.
