R-alpha: several bugs ...

[Kurt Hornik]

Perhaps I'd better not send any bug reports in order not to delay the
release of 0.50 ... but nevertheless.

R> x <- rnorm(20)
R> y <- rnorm(20)
R> z <- lm(y ~ x)

R> typeof(z)
[1] "list"

R> unlist(z)
[[1]]
[1] 0.07030757

[[2]]
[1] -0.1790483

[[3]]
NULL

[[4]]
NULL

and many more ending in

[[152]]
NULL

[[153]]
NULL

[[154]]
NULL

Hmm ...

*****************************************************************

Also, it seems that effects.lm, predict.default for lm objects,
update.lm and even formula.lm do not work.

E.g., predict.default does not take care of the one-arg case (and hence
dies when calling as.matrix on NULL), and in the 2-arg case tries to use
object$intercept and object$covmat which do not exist (in the lm case).

Hmm ... this is not meant as a `usual' passive bug report.  Is anybody
working on fixing these problems?  If not, I am willing to have a look,
but I can't promise that I'll get it done within very soon.

R&R, do we have a scheduled release date for the next version?

Best,
