Hello ALL!
I have a problem to plot factor (lets say gender) as a line, or at least
both line and point, from ols model:
ols1 <- ols(Y ~ gender, data=dat, x=T, y=T)
plot(ols1, gender=NA, xlab="gender", ylab="Y",
ylim=c(5,30), conf.int=FALSE)
If I convert gender into discrete numeric predictor, and use
forceLines=TRUE, plot is not nice and true, since it shows values
between 1 and 2.
Thanks!

Petar,
forceLines seems to be doing what it was intended to do. I'm not clear
on why you need a line, though. If you provide self-contained code and
data that replicate your problem I may be able to help more, or you can
try a new package I'm about to announce.
