Hi
I have the following code which I would like to simplify. Id does linear
regressions and returns the r-squares, and the coefficients.
It runs slow, as it is doing the regressions for each - is it possible
to get the values in a dataframe which looks as follow:

I think your script is slow because it has to recalculate the same model
five times. I've tried to avoid this by rewriting your function(df).
function(df){
fit - summary(lm(distance ~ generation, data=df))
result - c(fit$$r.squared
