[R] (no subject)

[Jordi Altirriba Gutiérrez]

  Dear R users,
  First of all, thanks for the incredibly fast answers and help of Rolf, 
Marc and Robert.
  Yes, I noticed that it was a lot of permutacions, but my intention was to 
make this process automatic and take only 5.000 - 10.000 permutations. 
Therefore, I wanted only to take that "interesting permutations" with "some 
information" [inter-block permutations].
  The reason why I'm interested in these permutations is because I'm using 
some packages of Bioconductor to analyse my data from some microarrays and I 
thought that perhaps could be interesting to see what happens when I permute 
my data and I compare it against the not permuted data.
  Thanks again for your time and suggestions.
