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)

To call in the statistician after the experiment is done may be no more than
asking him to perform a post-mortem examination: he may be able to say what the
experiment died of.

The combination of some data and an aching desire for an answer does not ensure
that a reasonable answer can be extracted from a given body of data.

Onderwerp: [R] CPU usage while running R code
I am currently running an R program on a computer with 16 Gb memory (Windows7,
64 bit). 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?
