Hi Piet,
did you put an argument named `projections' in you lm call? If you look in lm.fit, then you'll see when this warning message appears. E.g.,:
x <- rnorm(100) y <- rnorm(100) lm(y~x, projections=5)
Call: lm(formula = y ~ x, projections = 5)
Coefficients: (Intercept) x -0.09678 0.16589
Warning message:
Extra arguments projections are just disregarded. in: lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...)
I hope it helps.
Best, Dimitris

Subject: [R] "disregarded projections" warning when fitting lm model
Hi all,
I'm fitting a linear model (using lm) to some 2500 data points. The model consists of 4 single terms and two combined terms. I get the following warning message:
"Extra arguments projections are just disregarded. in: lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) "
Can anybody clarify this ? I don't seem to find any pointer to what
this might mean. Too many/little data points ? too many terms in the
model ?
thanks
Piet
