rrcovNA Dependency

[ksamuk]

First off: thanks for making such a useful package!

Just a heads up that I am getting the following error when installing (on both my Windows and MacOS machines):

* installing the package to build vignettes
* creating vignettes ...Warning: running command '"C:/PROGRA~1/R/R-33~1.2/bin/x64/Rscript" --vanilla --default-packages= -e "tools::buildVignettes(dir = '.', tangle = TRUE)"' had status 1
 ERROR
Quitting from lines 187-202 (MINOTAUR.Rmd) 
Error: processing vignette 'MINOTAUR.Rmd' failed with diagnostics:
there is no package called 'rrcovNA'

As you might expect, it can be resolved by installing rrcovNA. But as it stands, the installer fails.
