[R] Very basic question regarding plot.Design...

[Petar Milin]

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!
