[R] R and excell differences in calculation F distributionfunction

[Luis Ridao Cruz]

R-help,

I'm trying to work out the density function by doing:

> df(5.22245, 3, 22)
[1] 0.005896862

> df(15.20675, 6, 4)
[1] 0.001223825


In excell the result is :

0.0071060464 <*>   FDIST(5.22245,3,22) 

0.0100001406 <-->   FDIST(15.20675,6,4)


>From my point of view the differences in the second case
are substantial.

Can anyone give me a hint on this?

Thanks in advance
