Problems with a dll under windows
I am trying to get a dll compiled for use with dyn.load. I use R.1.7.1
under Windows.
I have tried the following trivial example based on the "Writing R
extensions" manual.
rtest.h
--------
class X {
public:
X ();
~X ();
void Give7(double*);
};
class Y {
public: Y (); ~Y ();
};
rtest.cpp
---------
#include <iostream.h>
#include "rtest.h"
static Y y;

Mixed-effects model problem.
I'm trying to fit a mixed-effects model of the form
Y = a + bX + cZ + e
where X are fixed effects and Z are random. i.e., c is a vector of
random coefficients with mean 0. There is no "grouping" variable such as
would be used with longitudinal data.
Can the nlme package handle this sort of thing? Although it is a simpler
model than would be used with grouped data, I can't seem

Monotonic interpolation
Has anyone got a function for smooth monotonic interpolation of a
univariate function? I'm after something like the NAG function PCHIM
which does monotonic Hermite interpolation. Alternatively, montononic
cubic spline interpolation.
Please reply directly.

Suggestion for quantile.default()
I'm not sure who is responsible for quantile(), but I assume they read
this list. Ivan Frohne and I have produced a revision of the
quantile.default() function which enables the computation of alternative
sample quantile definitions. The code and .Rd file are attached.
This enables the user to produce quantiles that are equivalent to those
in various statistics package. There is a type

About building R1.6.1 on Cygwin
Hello.
For building REmbeddedPostgres in Omegat
project(http://www.omegahat.org/RSPostgres/) requiring PostgresSQL's libs,
I've tried to build R1.6.1 on Cygwin following the instruction of
http://www.stats.ox.ac.uk/pub/Rtools/ since full-spec PostgresSQL running on
Windows can run only on Cygwin environment,
However I've got following error messages.

Missing "spline_coef" DLL and Rob Hyndmans monotonic interpolator
Hello R help
I have been trying to use Rob Hyndman's monotonically increasing spline
function. But like another user or two seem have a problem with a
missing DLL (namely "spline_coef"). None of the previous help postings
seemed to have any solutions to this problem. As per a Ripley
suggestion I have deleted all previous versions of R and reinstalled R
2.7.0 and the problem

stats::median
The generic stats::median method is defined as
median <- function (x, na.rm = FALSE) {UseMethod("median")}
I suggest that this should become
median <- function (x, na.rm = FALSE, ...) {UseMethod("median")}
This would allow additional S3 methods to be developed with additional
arguments.
Currently I have to over-ride this generic definition in the
demography

median methods
Can we please have a ... argument in median() to make it possible to pass
arguments to specific methods.

Error in help file for quantile()
For some reason, the help file on quantile() says "Missing values are
ignored" in the description of the x argument. Yet this is only true
if na.rm=TRUE. I suggest the help file is amended to remove the words
"Missing values are ignored".

Moving Average
Dear R-Users,
How can I compute simple moving averages from a time series in R?
Note that I do not want to estimate a MA model, just compute the MA's
given a lenght (as excel does).
Thanks

linear model with arma errors
Dear all,
I'm looking for how can I estimate a linear model with ar(ma) errors :
y(t)=a*X(t)+e(t) with
P(B)e(t)=Q(B)u(t)
where u is a white noise and P, Q are some polynomes.
Could you help me ?

Need help with pipe()
Hello.
I have an R program that calls gawk (GNU Awk 3.06 for Windows) from
within pipe() to preprocess a large file before it is read into a data

I've recently upgraded from Win98SE to WinXP, and have also upgraded
from R1.5.0 to R1.6.1 over the past month or so. This program worked
before the upgrade(s), but now fails. I observe the following sort of

Search for best ARIMA model
Hello,
I have a several time series, which I would like to check for their best
fitted Arima model (I am checking for the lowest aic value).
Which lets me raise two questions:
1) is there are more efficient way, than using 6 for-loops?
2) sometimes the system cannot calculate with given parameters - is
there a more efficient solution than I found?
I hope, you can help me to make this

Proposed modification to decompose() and plot.decomposed.ts()
The decompose() function truncates the seasonal component
unnecessarily. I've modified the function to fix this problem, and
also added the original data to the object returned (to enable better
plotting).
I've also modified the plot.decomposed.ts() function so that it plots
the original data in the top panel rather than the reconstructed data.
The difference between the two is that the
