are you sure this is pass by value?
But that is what environments are for, aren't they?

Read section 2.1.10
Given S4 methods [ and [-, how do I write the Rd-file usage clause for
the latter one?
What I have now is:
\S4method{[}{TimeSeries,TimeDate,missing}(x, i, j, ..., drop)
\S4method{[-}{TimeSeries,TimeDate,missing,ANY}(x, i, j, ..., value)
which results in the following output:

Glad to see that we agree on this.

That's not how you use it, surely?
The obvious to me
\usage{
\S4method{[}{TimeSeries,TimeDate,missing}(x, i, j, ..., drop)
\S4method{[}{TimeSeries,TimeDate,missing,ANY}(x, i, j, ...) - value
}
works. There is an example of a replacement method using \method in
'Writing R Extensions', so

Hi:
Does anybody have some starter code in Java to instance a stand alone
JGRConsole ?
From the docs it looks that it shouldn't be that hard to write some starter
code:

But in practice starter code has always little
Would it make anyone any happier if the manual said
that the replacement functions should not be called
in the form
xNew - `func-` (xOld, value)
and should only be used as
func(xToBeChanged) - value
?
The explanation
names(x) - c(a,b)
is equivalent to
'*tmp*' - x

Dear R-devel,
It seems that lsfit incorrectly reports coefficients when the input matrix 'x'
is rank-deficient, see the example below:
## here values of 'b' and 'c' are incorrectly swapped
x - cbind(a=rnorm(100), b=0, c=rnorm(100)); y - rnorm(100); lsfit(x, y)$coef
Intercept a
