Hi all,
I'm having a hard time figuring out how to extract the p-value from a PGLS
model fitted in caper.
When I run summary(mod) and print it, I get, among other things:
>summ=summary(mod)
>summ
Coefficients:
Estimate Std. Error t value Pr(>|t|)
(Intercept) 0.0179553 0.0243379 0.7378 0.4613664
scaled_precip -0.0292664 0.0040679 -7.1945 7.474e-12 ***
scaled_temp 0.0162603 0.0048189 3.3743 0.0008592 ***
---
Signif. codes: 0 ‘***’ 0.001 ‘**’ 0.01 ‘*’ 0.05 ‘.’ 0.1 ‘ ’ 1
Residual standard error: 0.0148 on 247 degrees of freedom
Multiple R-squared: 0.1739, Adjusted R-squared: 0.1672
F-statistic: 25.99 on 2 and 247 DF, p-value: 5.69e-11
What I'm interested in is the very last value printed, 5.69e-11. But I
can't find where it's actually stored in the summ object. I've already
tried every $ in summ but don't see that value anywhere. How can I actually
extract it from the object?
Thanks!
