There was 1 NOTE across all environments:
GNU make is a SystemRequirements.
This appears to be related to using RcppParallel and does not seem problematic. GNU make has been added to SystemRequirements in the Description file.
In addition, on Ubuntu Linux, the package appears to be slightly larger than 5MB, around 6.3 MB. This does not appear to occur on any of the other environments however (i.e. Fedora Linux, Windows)
Finally, there is the following note on Ubuntu and Fedora Linux:
checking HTML version of manual ... NOTE Skipping checking HTML validation: no command 'tidy' found Skipping checking math rendering: package 'V8' unavailable
This seems build system specific and not directly tied to the package.
We believe this is an issue on the build server and not package specific.
