Hello,
I have a data frame and want to do the following.
Do a regression of one variable versus another:
fit <- lm(a ~ b)
Then I would like to plot the residuals of this fit versus a third variable:
bwplot(residuals(fit) ~ group)
This fails, if a or b contain NAs, because the data in the residuals() -
vector are not aligned anymore to the data in the original data frame.
Is there a way to solve this issue?
Regards and thanks for your help
Klaus
