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.
