R: update to 4.0.2.
https://github.com/void-linux/void-packages/pull/24126

Description:
This is a major version update to R with some breaking changes for older R packages/scripts. Although the problems with most CRAN packages should be resolved as CRAN gave package authors a deadline to submit fixes. I've been using R 4.0 for a couple of months now and not experienced any problems.

## Breaking Changes

- Packages need to be (re-)installed under this version (4.0.2) of R.
- R now uses a stringsAsFactors = FALSE default, and hence by default no longer converts strings to factors in calls to data.frame() and read.table(). A large number of packages relied on the previous behaviour and so have needed/will need updating.

## Build Changes
- This version of R is built against the PCRE2 library for Perl-like regular expressions, if available.
- Enable memory profiling by building with --enable-memory-profiling flag, this is the default on all binaries provided by upstream, and several other distros.

## Dependencies to Build and Check

Some R-cran-* packages failed xlint, so I've changed those where appropriate.
