One of our R users here just showed me the following problem while
investigating the return value of a while loop. I added some

but I see the same problem on today's development version of 2.10.0
(svn 48703).

Vectorize is defined to return a function that acts as if 'mapply' was
called.
So we have:

1L # calls dput on each element of 1:2
2L
[1] 1 2
> Vectorize(dput)(1:2)# Vectorize form

I'm in the process of coding a parser (in C) to generate R entities

%in% is a thin wrapper on a call to match(). match() is
not a generic function (and is not documented to be one),
so it treats data.frames as lists, as their underlying
representation is a list of columns. match is documented
to convert lists to character and to then run the character

Hi Everyone,
I am getting a warning when I build and package from windows. The warning is
"some HTML links may not be found". Through some searching I found this
probably has to do with the Microsoft HTML Help Workshop, but I have installed
it (a few times) from the different locations in the m

Dear R-developers,
It seems to me that the position of title is usually at the bottom of
a plot in sociological and political science books and articles. I
wonder if the same convention applies in other disciplines. If yes, is

In fact reg.finalizer() looks like a dangerous feature.
If the finalizer itself triggers (implicitely or
explicitely) garbage collection, then bad things happen.
In the following example, garbage collection is triggered
explicitely (using R-2.9.0):
