The link_again function can relink the R language with the OpenBLAS library. Thus, link_again will only perform the
relinking when the ropenblas function has been used in a previous R session for the initial binding of the R language with the
OpenBLAS library.
Relinking is useful in situations of operating system updates. In some updates, it is possible that the OpenBLAS library compiled
in the /opt directory gets unlinked. In this scenario, when the OpenBLAS library has already been compiled using the ropenblas
function, the link_again function performs a new link without the need to recompile, thus making the process less time
consuming.
