StructTS
I apologize in advance if I picked the wrong list to post this to. I have made an effort to find the answers to these questions on CRAN, but if they are there, I couldn't find them, and I was going to email the developer of StructTS directly but could not find who that is. I have 2 interrelated questions about StructTS 1. Where can I obtain the source code for StructTS if I wanted to

R for Windows 32-bit mode versus 64-bit mode
Hi All: We are developing (actually updating) a piece of code that runs in R. Due to some limitations of some the libraries we use, at the present time we would be limited to the 32-bit version of R on Windows. Does anyone have a feel (or even real knowledge) if most people these days run R on Windows in 32-bit or 64-bit mode? This would affect some development decisions. Thanks -Roy M.

[OT]Web-Based Data Brushing
I apologize for the off-topic post, but my Google search did not turn up much and I thought people on this list my have knowledge of this. I am looking for examples of data brushing (i.e. dynmaic linked plots) either on a web site, or in a web-based application, such as an AJAX app. Even better if there is a way to do this in R. Thanks for any help. -Roy M. **********************

In fact all I want is the (exactly) 7-digit number before ".html". The good news is that as far as I can tell the the <a>

HIRHAM netcdf files
Can someone help me out with a "small" problem? I've started using netcdf files recently, and I want to extract the grid id and also the coordinates from a HIRHAM netcdf file. I know how to extract a slice of dataset both in space and in time and I also know the area that this file should cover, however I have no idea regarding the reference for both LAT/LON and RLAT/RLON. I tried

World Ocean Database files
Has anyone written a script or function to read data from NODC?s World Ocean Database files? (I know there are simple Fortran and C programs to read these files, but the output is not suitable for easy analysis) Thanks, Franz _____________________________________________________ Dr. Franz J.

Popbio - can't find or load
Hello, I'm in need of running a PVA and want to load {popbio}. However, I can't find it. I can't see where or how to load it. I have added repositories and changed the CRAN mirror site. I see {polynom} and {popgen} but no {popbio} between. What am I doing wrong? Thanks, Michelle [[alternative HTML version deleted]]

r-forge down?
Hi Folks, I've looked around, haven't found anything, and I'm not sure where else to check. I haven't visited R-forge (http://r-forge.r-project.org) in a long time. Now that I'm trying, it seems to be down. Anyone know if this is a temporary condition, and if so, when it's expected to rise again? Thanks, Allie

Create a function "automatically" from lm formula and coefficients?

time-series trend classification
Hello everyone, I was looking for a way to classify time-series based on the curve-fit. I try to campute several trends so i was thinking to link each trend with a function. increase with exponential for example, increase and decrease with a gaussian etc. The possiblities are endless though and it seems that is not always working well, especially if you work on small time-series (of 5-10 points

generalized least squares with empirical error covariance matrix
I have a bayesian hierarchical normal regression model, in which the regression coefficients are nested, which I've wrapped into one regression framework, y = X %*% beta + e . I would like to run data through the model in a filter style (kalman filterish), updating regression coefficients at each step new data can be gathered. After the first filter step, I will need to be able to feed
