OT: BibTex year-only citation in text?
Sorry for the off-topic question, but I know there are some talented LaTeX users out there. Which bibliography style gives only the year in text citations (e.g "for further details, see Anderson (1992)" )? Thanks Jason -- Indigo Industrial Controls Ltd. http://www.indigoindustrial.co.nz 64-21-343-545 jasont at indigoindustrial.co.nz

Summary --- testing for existence of file.
Many thanks to those who answered my question about how to test for the existence of a file: Berwin Turlach, Jari Oksanen, Henrik Bengtsson, Uwe Ligges, and Joerg Maeder. The simplest solution is to use the built-in (!!!) function file.exists() which returns TRUE if the file exists, and FALSE if it doesn't. Like, duhhhhhh!!! It's exactly what I wanted. Special thanks to Berwin Turlach

Question about the high dimensional density estimation
Hi, I found that the R package "KernSmooth" can deal with only 1D and 2D data. But now I have a collection of 4-dimensional data (x1,x2,x3,x4) and would like to estimate the "mode" of the underlying density. What can I do about it ? Thanks a lot. -- Ying-Chao Hung Assistant Professor Graduate Institute of Statistics National Central University Chung-Li, Taiwan TEL:

run R under linux
Dear all, Our department uses the linux system and we are not allowed to submit job directly. We must make a batch to submit through "qmon". so, I make a foo.sh file, which only contains one line: nohup R --vanilla < foo.txt > foo.results foo is all my codes. It is a simulation of 200 times. I set the seed at the beginning. It is to estimate the success probability, which is

Sweave/LaTeX Problem with EPS PDF
Dear List: I am unsure if my problem is with Sweave or LaTeX. Anyhow, I am using the MikTeX distribution and TexnicCenter. I can easily create Sweave files and all goes well until I try to incorporate graphics. I use the same code as found in the examples found in the users manual. In R, the graphics I want are created as Sweave is creating the .tex file. When I examine the .tex file

bug in as.POSIXct ?
I think that there is a bug in the as.POSIXct function on Windows. Here is what I get on Win2000, Pentium III machine in R 1.8.1. > dd1 <- ISOdatetime(2003, 10, 26, 0, 59, 59) > dd2 <- ISOdatetime(2003, 10, 26, 1, 0, 0) > dd2 - dd1 Time difference of 1.000278 hours Now, the 26th of October was the day that change to the standard time occurred, so I suspect that this has

Can I build an array of regrssion model?
Hi, I am trying to use piecewise linear regression to approximate a nonlinear function. Actually, I don't know how many linear functions I need, therefore, I want build an array of regression models to automate the approximation job. Could you please give me any clue?

trouble with netCDF (PR#824)
Having trouble with netCDF since I upgraded to 1.2.1 (did directly from 1.1.1). Package was recompiled after the upgrade. Symptoms: open.netCDF returns cleanly, but read.netCDF causes R to segfault and dump core. What else do you need me to write to help? --please do not edit the information below-- Version: platform = i586-pc-linux-gnu arch = i586 os = linux-gnu system = i586, linux-gnu

help.start( )
Dear R experts, I installed R-1.7.1 on Linux (Red Hat 9.0) starting from R-1.7.1.tgz without a problem. Then I fired up R and tried things and found that help.start( ) does not work. I downloaded Sun Java j2re1.4.2, installed that and re-installed R-1.7.1 from scratch. I tried help.start( ) again and the browser (Mozilla 1.2.1) crashed.

using "by" and indicies
I sent this to the list last week, and haven't seen it pop up. Either I deleted it when it did appear, or possibly it was destroyed as spam...? If it did appear and I somehow missed it, appologies. In a nutshell, can the function FUN supplied to by() deduce what level of factor by() was on when FUN was called? I've been digging through the functions, and can't see where the

Updating a linear model
