Raffa, I ran this on a MacOS machine and got what you expected. I added a call to sessionInfo() for your information. > rm(list=ls()) > N = 3 > xvar <- runif(N, -10, 10) > e <- rnorm(N, mean=0, sd=1) > yvar <- 1 + 2*xvar + e > plot(xvar,yvar) > lmMod <- lm(yvar~xvar) > print(summary(lmMod))

[R] Increasing number of observations worsen the regression model

I have the following code: ``` rm(list=ls()) N = 3 xvar <- runif(N, -10, 10) e <- rnorm(N, mean=0, sd=1) yvar <- 1 + 2*xvar + e plot(xvar,yvar) lmMod <- lm(yvar~xvar) print(summary(lmMod)) domain <- seq(min(xvar), max(xvar))    # define a vector of x values to feed into model lines(domain, p
