[R] extracting P values from lm model

2010-11-29 Thread Rosario Garcia Gil 
Hello

I am trying to get out of an lm model the fstatistics, however after I run the 
model I write 
 names(Model)

and the fstatistic does not appear only these.

names(Model)
 [1] coefficients  residuals effects   rank  
fitted.values
 [6] assignqrdf.residual   xlevels   call 

[11] terms model  

How could I extract the P values? I have run a cbind of 1800 response variables 
so is not easy to do it by hand.

Thanks in advance.
Rosario

Rosario,
 The summary function will compute the f-statistic, from which you can 
compute the attained p-value. Here's a snippet that shows the f-stat.

summary(lm(Y ~ X))$fstatistic
   valuenumdfdendf 
34.23125  1.0  8.0
