Dear Laurent, An R proces uses only one core. It is possible to use multiple cores. Have a look at he Hig-Performance and Parallel Computing task view (http://cran.freestatistics.org/web/views/HighPerformanceComputing.html)

When I look at the task manager, I see that only 4 out of the 8 CPUs are being used. Is this due to some missing in the R code, or should I change something to the settings of the computer?
