This is not an R-devel question, so please do not reply to this list.
I would try
sapply(strsplit(loaded.topics$doc.id, "_"), function(xx) xx[1])
to get the MD part.

I have a table with a structure like the following:
lang | basic id | doc id | topics|
se | 447157 | MD_2002_0014 |12 |
loaded topics <- read.table("path to file",header=TRUE, sep="|",
fileEncoding="utf-8")
In that table the actual meaningful data (in this context) is the text

Hi all,
I would like to include a function that I have made by modifying an
existing R function (bw.SJ and corresponding code in bandwidths.c).
The header of bandwidths.c states:
/*
* R : A Computer Language for Statistical Data Analysis
* bandwidth.c by W. N. Venables and B. D. Ripley Copyr
*Hi,
first of all-thank you for your extensive answer.*

Of course not. What I hope can happpen is that we can reduce the
degree to which internal implementation quirks leak out into the user
level. The fact that there is an internal "missing token" (that
happens to be used for a couple of different things) is a quirk; if
you look at the code I use you
In general, should we expect that the ability to compute on the
language within R will decrease over time? Otherwise, I presume if you
do change the behaviour of missing then you'll still provide some way
to create/call functions with missing arguments.

I wouldn't count on any way of capturing this thing being reliable in
the long term. As I recall what I do in codetools and the compiler is
use features of missing() to test for it, but try to abstract those
uses into one or two places only so I can easily change them if
missing()'s behavior chan

Hi all,
I think there's a small buglet in quote:
str(quote())
# Error in quote() : 0 arguments passed to 'quote' which requires 1
str(quote(expr = ))
# symbol
I bring this up because this seems like the most natural way of
capturing the "missing" symbol with pure R code, compared to
substitute()

No one yet has mentioned shiny (http://www.rstudio.com/shiny/); it
allows you to get up and prototyping quickly, and we're working on
ways to make it just as easy to scale to multiple users (currently
it's possible, but you have to be willing to get your hands dirty
configuring servers etc).

Brian,
I used termplot(..., plot=FALSE) recently in R-devel: works like a charm. Thanks much
for the update.
Our in-house "gamterms" function, which this obviates, would also return the "constant"
attribute from the underlying predict(..., type="terms") call. I have occasionally found

i have looked at apache, but there is no Windows version (at least to my

I know how to connect to MS SQL from R, i just dont know how to do that from

Hi,
i think all of this i kinda complicated, even though in all the packages
authors are saying that "minimum code is required".

Hi!
The nobs() method for glm objects always returns the number of cases
with non-null weights in the data, which does not correspond to the
number of observations for Poisson regression/log-linear models, i.e.
when family="poisson" or family="quasipoisson".
This sounds dangerous since nobs() is,

First of all you should as this question on r-help rather than on r-devel
as this group deals with development related issues with R.
As for the package you can use the shiny package from Rstudio. I have
provided the links below.
