I have encountered the following problem while doing "Appendix A A simple session"
p.84 in The Intro to R :
> fm1 <- lm(y ~ x, data=dummy, weight=1/w^2)
Error in lm.wfit(x, y, w, offset = offset, singular.ok = singular.ok, :
NA/NaN/Inf in foreign function call (arg 1)
What seem to be the problem?
Yours Truly,
