Aggregate linear regression

Question

Sorry I am quite new to R, but I have a dataframe with gamelogs for multiple players. I am trying to get the slope coefficient for each player\'s points over all of their games.

Answer 1

library nlme has a function for this as well, lmList

library(nlme)
coef(lmList(game ~ pts | name, gamelogs))
#        (Intercept)         pts
# player1    7.714286 -0.42857143
# player2    4.230769  0.08241758
