The maximum length of a character string returned by strwrap,
i.e. max(nchar(strwrap(x,width))), never in my experience exceeds
width-2 (unless x contains a word that is longer than this).
This is not exactly a bug -- width is described only as a "target
column for wrapping lines" -- but seems odd.
The documentation for tempdir() and tempfile() on R-2.2.1 for Windows
says that "Both will use backslash as the path separator", but in
practice I see a forward slash:

The documentation for lm() indicates that the 'qr' component of an
lm object is optional. But some functions do not behave well when
this component is absent: summary() gives an error and predict()
returns all zeroes.
Example:

> mm <- lm(y~x, qr=FALSE)

Levels: a
I would have expected f2 to have only one level, "a". It seems
to me that the code in [.factor does not follow the advice in
help("factor") on how to set factor co
