R help - Mar 2018 - How to Find the value of r-square change in hierarchical multiple linear regression

Dear list members,

I'd like to find the value of r-square change at each step of a
regression model.

I know that I can use anova () to compare to models, but, if I want to
find out that how much exactly r-square has  change from one model to
the next, how can I find that?

Regards, and thanks for any help.

See ?summary.lm

For a linear model L
summary(L)$r.squared

gives R^2

and the adjusted R^2 is
summary(L)$adj.r.squared
