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 value numdf dendf 34.23125 1.00000 8.00000 Dave From: Rosario Garcia Gil <m.rosario.gar...@genfys.slu.se> To: r-help <r-help@r-project.org> Date: 11/29/2010 09:30 AM Subject: [R] extracting P values from lm model Sent by: r-help-boun...@r-project.org 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] "assign" "qr" "df.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.
