Sorry for my silly questions. I'm a beginner with R and most statistics
concepts.
I carried out a simple linear regression where the dependent variable is
explained through a combination of powers
of cos(independent variable).
I can see R returned a good R^2 factor (> 0.99) but I have a hard time at
interpreting all the other info that R prints out by using summary(
regression.results), residuals(regression.results), anova(regression.results),

plot(regression.results).
I know sometimes R^2 might be misleading ..

I see that R provided a Q-Q plot by default.
Is it possible to get a P-P plot ? I searched for that but did not get
anywhere ...

Thank you in advance.
Best regards,
