Re: [R] How to plot

you could use directly the plot function on an `lm' object, e.g., x - runif(100, -3, 3) y - 1 + 2*x + rnorm(100) m - lm(y~x) par(mfrow=c(2,2)) plot(m) This doesn't produce the I Chart you wanted but it gives a very good picture about any strange behaviour of the residuals. I hope it helps. Best,
