Extractor function for standard deviation.
I have from time to time seen inquiries on r-help in respect of
how to obtain the estimated standard deviation from the output of
fitting a linear model. And have had occasion to want to do this
myself.
The way I currently do it is something like summary(fit)$sigma
(where fit is returned by lm()).
It strikes me that it might be a good idea to have an extractor
function, analogous with coef()

easy way to find all extractor functions and the datatypes of what they return
Am I asking for too much:
for any object that a stat proc returns ( y <- lm( y~x) , etc ) ) , is there
a super convenient function like give_all_extractors( y ) that lists all
extractor functions , the datatype returned , and a text descriptor
field ("pairwisepval" "lsmean" etc)
That would just be so convenient.
What are my options for querying an object so that I can

We have published two papers which build upon the LLVM
Compiler Infrastructure. Would it be possible to include them in the
LLVM related publications at http://llvm.org/pubs/ ?

[LLVMdev] Loop Extractor
llvmers,
Is it possible to change the loop extractor to extract each nested loop
into it's own function, including the top level loop? I would like to put
every loop into it's own function.
Thanks.

spatstat => owin + image
Dear Community
I am at my wits end and seek advice.
My wish is to plot coordinates (x,y in WGS84_UMTS for the ones interested)
of sampling points.
This I can do by the standard spatstat prodcedure via owin. I then try to
add an image, which is
a map/satellite photo in the background.
Firstly
Problem: With the current code, I can not get the edges of the image to
match the boarders of the plot

Street Atlas 8.0 Extractor
I mentioned earlier that I had DeLorme Street Atlas 8.0 working on
wine. It comes with a separate program, the extractor. This will pull
parts of the map CD and store them locally so that the main program
does not have to refer to the CD for those parts of the map.
I had one problem which I overcame: it was looking for h:\refnc. I
have no idea why it was looking on h:, as the CD-ROM is on d: and

Willkommen bei der "R-help" Mailingliste
Hello everbody,
I am new to this mailing list and hope to find some help.
I'm trying to get into the spatstat package and encountered two problems. First a graphical one:
There is an example dataset called "finpines" which has several marks (http://www.oga-lab.net/RGM2/func.php?rd_id=spatstat:finpines)
When I pass the given code from the website to R

Re: using shapefile as owin
My sincerest apologies, as this is a very elementary problem, but I have
searched through archives and FAQs and on the web, and I am at the end of my

counties, using spatstat. I've had no trouble importing the shapefiles, but
I can't seem to figure out what I need to do in order to use the boundary as

Spatstat - coordinates in observation window
Dear R users,
I wish to run spatial point pattern analysis (e.g. pair correlation function, mark correlation function) for which I need to create an observation window (window=owin) from which the spatial analysis is generated. The command I used to create this observation window as follows:
X1<- ppp(x, y, window=owin(c(80.58,144.96),c(101.06,165.13)),

Samba -> WinXP: slow transfers, partial solution
Hello All,
I'm running Samba 3.0.24 as PDC and file server on Gentoo Linux,
AMD64, 2.6.19 kernel, 100MBit/s network, and experience quite slow
file transfers from Samba to WinXP SP2 clients: the speed is varying,
but is about 1-2Mb/s at best.
I spent quite some time investigating the issue, here are the
intermediate results:
