I think you don't need to write temp.data$a ~ temp.data$b just a ~ b

Dear R-helpers,
In my dataset I have two continuous variable (A and B) and one factor.
I'm investigating the regression between the two variables usign the command
lm(A ~ B, ...)
but now I want to know the regression coefficient (r2) of A vs. B for every
factors.
I know that I can obtain this

Yes Dimitri that's what I mean!
Something like this?
for(i in levels(c)) { lm(a ~ b * c , data=mydataset)}
And what about to see the output?
Thanks!

First you have to create something (e.g., a list) that holds your
output:
mylist-NULL
Then you loop through the levels of c and run
