lapply and SpatialGridDataFrame error
Hi all, I have a set of 54 files that I need to convert from ASCII grid

I have the following R code to operate on those files:

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(y ~ sx(x), method = "REML", data = dat)

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.

library(BayesX)

Two questions about R2BayesX package
Dear All,
I have two questions regarding the use of the R2BayesX package for Bayesian
analysis. First, is it possible to generate predictions based on the fitted
model? According to Gelman and Hill (2007, pp. 361-363), there are at
least two ways to do this in BUGS: (1) generate additional data points with
the dependent variable coded as missing (and all the independent variables

unable to load shared object - opencv
Hi all
i'm trying to use the opencv's function into R.
i wrote a simple script, just for try to understand how use c++ in R, it
loads an image and write it with a different name (i know it ), and then
write "Hello, World". The file is names prova2.cpp (is the first time i try
to use c++ )

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

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

Selecting derivative order penalty for thin plate spline regression (GAM - mgcv)
Hi,
I am using GAMs (package mgcv) to smooth event rates in a penalized regression setting and I was wondering if/how one can
select the order of the derivative penalty.
For my particular problem the order of the penalty (parameter "m" inside the "s" terms of the formula argument) appears to
have a larger effect on the AIC/deviance of the estimated model than the

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

Invalid read of size 8
Hi,
I have a R program that call a C function. I define a vector of pointer as
int nLC=3;
int pownLC = nLC*nLC
double *MatCovExtra[nT+1];
for(k=0;k<K+1;k++)
{
MatCovExtra[k] = (double*)R_alloc(pownLC, sizeof(double));
}
where nT>K. Then i put some values on the vector associated with the
pointer:
for(k=0;k<K+1;k++)
{

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
