hi,

can anyone help me about the simple data probability-value of the F-test,
respectively p-value, shown in the summary of a linear model?
somehow i can not retrieve this data out of R+ into my sql-dataset. i can
get all other data shown with the command: 
summary(speciallinearmodel) - will have a gui screen

Call:
lm(formula = y21 ~ x4 + x18 + x4:x18, data = clustertransformationstabelle)
Residuals:
Min       1Q   Median       3Q      Max

Residual standard error: 0.1305 on 91 degrees of freedom
Multiple R-Squared: 0.7865,     Adjusted R-squared: 0.7795 
F-statistic: 111.7 on 3 and 91 DF,  p-value: < 2.2e-16 

but the desired p-value like in this example p-value: < 2.2e-16, i somehow
can not retrieve by any command like attributes(speciallinearmodel).
has anyone an idea to get this shown but not selectable respectively
exportable p-value?
