WebIt’s no surprise that R has a built in function, lm (), that will estimate these regression coefficients for us. The function can be called as follows: M <- lm( y ~ x, dat) The output of the linear model is saved to the variable M. The formula y ~ x tells the function to regress the variable y against the variable x. brother tough and strong sewing machine https://theprologue.org
