I'd like to know why I cannot get a plot and the QQnorm in the same sheet.
The commands are simple but:
library(nlme)
glmod1 <- gls(upfmla,correlation=corAR1(),method="ML")
summary(glmod1)
par(mfrow = c(2,1))
plot(glmod1, main="GLS Residuals vs. GLS Fitted")
qqnorm(glmod1)
No matter what (I tried different permutations of the plotting commands) the
second drawing is overlapped to the first one instead of being placed
underneath it on the same page.
How come?
Thank you very much.
Happy New Year,
Maura
