Uh-oh, please do not abuse the friendly nature of this list for non-related
topics.

There are r-help, StackOverflow, the excellent r-pkg-devel and more.

| 
| R CMD check BHPMF_1.0.tar.gz
| 
| using current R 3.6.2. This command compiles and installs the package
| and runs different checks on it. The result were two warnings:
| 
| * checking whether package ‘BHPMF’ can be installed ... WARNING
| Found the following significant warnings:
|   utillity.cpp:293:15: warning: ignoring return value of ‘int
| fscanf(FILE*, const char*, ...)’, declared with attribute
| warn_unused_result [-Wunused-result]
| [...]
| * checking for portable use of $(BLAS_LIBS) and $(LAPACK_LIBS) ... WARNING
|   apparently using $(BLAS_LIBS) without following $(FLIBS) in ‘src/Makevars’
| 
| Warnings like this this are sufficient to have a package removed from
| CRAN. They should be easy enough to fix, though.

r-pkg-devel seems like a good venue for general R package tips.

Good luck,  Dirk
