The equibalent in R of P = fcdf(X,V1,V2) (as in your URL) is

  P <- pf(X,V1,V2)

where X,V2,V2 should be vectors of the same length.

Note that R's pf offers additional functionality, such as a
non-centrality paramater for the no-centgral F distribution.

Enter '?pf' for more detailed information.
