There is no error appeared for this command, but when I use the command “ is.loaded” to check, it shows that dll file isn’t be loaded.

I never used VC (Mingw's gcc is recommended), but I can tell you that
there is some information in .../src/gnuwin32/readme.packages and I
think also in Venables&Ripley (2000): S Programming, Springer (but not
sure about that, since the latter is in my office).
