[R-sig-Debian] Cpp Error installing CRAN version of MatrixExtra on Ubuntu 18.04

[David Winsemius]

I initially attempted installation of pkg:MatrixExtra with 
`install.packages on my Ubuntu 18.04 LTS system from within RStudio. It 
failed with an error attempting to compile a function named "matmul.cpp" 
so I tried running R from a Terminal session. Same error. Finally I 
downloaded from CRAN and this is the session result of an effort with R 
CMD INSTALL:

(The name of my library is a historical accident, but I'm running R 
version 4.1.2 (2021-11-01) -- "Bird Hippie" and almost all of my other 
1536 packages have been updated without reported errors using 
`update.packages(checkBuilt=TRUE)`
