Hi,
I want to plot the residuals of a least-squares regression.
plot(lm(y~x), which=1)
does this, but it plots the y-axis of my data on the x-axis of the
residuals plot. That is, it plots the residual for each y-value in the
data. Can I instead use the x-axis of my data as the x-axis of the
residuals plot, showing the residual for a given x?
Thanks!
