Believe or not, it works.

I did this because I did not find good examples about how to link Lapack
and Blas using R. So I tried this and it works.

I did find an R package which uses Makefile in its src directory, and I
just happened to be familiar with. But it was on the author's website
and not on CRAN. Maybe that's a bad example. I will take a look at that

This is mine. I agree with you. Certainly there are more stuff I need to
know about 'Writing R Extensions'. The package is on my website, see
below. Using the following:
#R CMD check cts
#R CMD INSTALL cts
I have successfully installed the package. Thanks for your advice. On
the other hand, it might be a successful story how R is robust!
