Hi!

I've used coef(lm(y~x))[[1]] and coef(lm(y~x))[[2]] to extract the intercept; but while summary(lm(y~x)) prints R-squared... it isn't entirely obvious how to extract this value as a scalar. ?lm doesn't give me the information

by saying

unlist(summary(lm(y~x))) it prints

$r.squared

[1] 0.2673333

so now I can say

my.r.sq <- summary(lm(y~x))$r.squared

but is there a better way? on my small lm model unlist(lm(y~x)) is a pretty long list! :-)

Many thanks in advance,

Sean O'Riordain
