lapply and SpatialGridDataFrame error
Hi all, I have a set of 54 files that I need to convert from ASCII grid
format to .shp files to .bnd files for BayesX.
I have the following R code to operate on those files:

library(BayesXsrc)
library(R2BayesX)
readfunct <- function(x)

extended Kalman filter for survival data
If you mean this paper by Fahrmeir: http://biomet.oxfordjournals.org/cgi/content/abstract/81/2/317 I would recommend BayesX: http://www.stat.uni-muenchen.de/~bayesx/.
BayesX interfaces with R and estimates discrete (and continuous) time survival data with penalized regression methods.
If you are looking for a bona fide Bayesian survival analysis method and do not wish to spend a lot of time coming up and debugging your...

Predict in the package R2BayesX
Hi all
I'm using the function bayesx to estimate a simple model, for example:
library(R2BayesX)
## generate some data
set.seed(111)
n <- 200
## regressor
dat <- data.frame(x = runif(n, -3, 3))
## response
dat$y <- with(dat, 1.5 + sin(x) + rnorm(n, sd = 0.6))
## estimate models with
## bayesx REML and MCMC
b1 <- bayesx...

R2BayesX help
Hi,
I wonder if anyone can help me with this issue. I am using R2BayesX. It
seems that the model can maximally contain 20 interactions. When the number
of interaction terms exceed 20, the code stops working. Here is a piece of
toy code.
rm(list=ls())
library(BayesX)
library(R2BayesX)
#data generating model
f2<-function(x1,x2,x3,x4)
{
y<-2*sin(pi*x1)*1.5+exp(2...

paraPen in gam [mgcv 1.4-1.1] and centering constraints
Dear Mr. Simon Wood, dear list members,
I am trying to fit a similar model with gam from mgcv compared to what I
did with BayesX, and have discovered the relatively new possibility of
incorporating user-defined matrices for quadratic penalties on
parametric terms using the "paraPen" argument. This was really a very
good idea!
However, I would like to constraint the coefficients belonging to one
penalty matrix to s...

Selecting derivative order penalty for thin plate spline regression (GAM - mgcv)
...higher values of m and different bases (thin plate, p-spline).
The overall significance of the smooth term changes, but is <0.05 in both cases, however the interpretation afforded by the
shapes of the smooths are different.
Smoothing the same dataset with a different approach to GAMs (BayesX) results in shapes that are more like the ones I have been getting with m>=3 rather than m=2 (I have not tried the conditional autoregressive regressions of WinBUGS yet).
Any suggestion on how to proceed to test the optimal order of the penalty would be appreciated. The 2 approaches I am think...

Checking package licences including dependencies?
I only recently discovered options("available_packages_filters" =
list(add = TRUE, "license/FOSS")) [cf. help("available.packages",
package="utils") in R 2.10.0 or later] which goes nicely with my
options("checkPackageLicense" = TRUE) [new in R 2.11].
But now I want to purge my library of packages I would not have
installed had I known about

Does "sink" stand for anything?
Hello Everyone,
Learning about R and its wonderful array of functions. If it's not obvious, I usually try to find out what a function stands for. I think this helps me remember better.
One function that has me stumped is "sink." Can anyone tell me if this stands for something?
Thanks,
Paul
