I think it is ESS that is parsing this as a help request (so it can divert
it to an ESS buffer).
Looks like this is an ESS issue, not an R one.
Using ?"agrep " will fail in R, but that seems correct as there is no
topic "agrep ".

This isn't particularly helpful because the book is quite old but
formula notation/functionality is covered in depth in "Statistical
Models in S" by
Chambers and Hastie. My guess is that there is strong consistency
between what is said in there and how things work in R.

In working through material on p.272 of MASS (4th ed.), I came
across the following model formula:
pet1.lm <- lm(Y ~ No/EP - 1, Petrol)
I was at a loss to understand the use of "/" until I looked in
"An Introduction [!] to R," where I found the explanation.
My request is that more complete mate

My conception of how NAMESPACE and methods in R-2.7.0 resolved a
generic 'func' to a func-method was to search as follows:
In 2.7.0:
func -->
NAMESPACE, including Imports: (and other details) -->
.GlobalEnv, and eventually Depends: since these are on search()
In R-devel it seems like

We don't know how to reproduce this: 'whitespace' is not specific enough.
R's tokenizer breaks input at spaces, so a space would never be part of
that expression. And tabs don't even get to the parser in interactive
use, and you cannot mean a newline. So exactly what do you mean by
'whitespa

Try replacing the last line in g with:
lmout <- do.call(lm, list(Formula, data = data, weights = w))
coef(lmout)
or replace w with environment()$w thereby explicitly telling it where to look.

Here's a simplified reproduce example:

Results in:
No documentation for 'agrep ' in specified packages and libraries:
you could try 'help.search("agrep ")'
There is white space after agrep, that ? doesn't ignore.

We are successfully building R and packages with the Intel 10.1
compilers on RHEL4 (except a few packages, which will not compile with
10.1, but with 9.1). We also use the Int
