Code for Hodrick-Prescott Filter: Special Case of smooth. spline?
I've had a play with this and, due to my own short-comings, remain none the
wiser.
In particular, I'm not sure what value of 'spar' is consistent with the
magic lambda=1/1600 for quarterly data.
I initially interpreted spar as lambda and tried setting spar=1/1600. This
results in almost no smoothing while spar=1600 causes an error. The
smooth.spline function seems to want

readline?
We've recently "upgraded" a server to solaris 8, and in reinstalling R
I've encountered a problem in getting it to recognize the readline library.
I have installed readline in what I believe to be the "usual" place:
/usr/local/lib with include files in /usr/local/include/readline.
But ./configure produces:

pause
I've been playing with a quincunx animation in R 1.2.2 and would like to have
finer control over the speed of the animation. I know that I can
use system("sleep 1") on unix systems at least, but it would be nice
to have something like pause(.01). Any suggestions?

About 2 percent of the time I use fix() to edit a function that is

translation from the old-S
In ancient times, circa 1980, S data directories were called swork and sdata
not .Data, and "New-S" as described in the already medieval "Blue Book"
discusses a function DBCONVERT that converted swork data into .Data data.
It is embarrassing to admit it, but I still have data archives from a BTL
machine called alice in the swork format and would like to convert a dataset

rbind(NULL,NULL)
In the time honored spirit of wishing to do nothing well, could I suggest
that the Splus (versions 5 and 6) response to:

image axes
I'm plotting matrices with image() and would like the axes to reflect
the conventional view that the upper left corner of the plot is (1,1).
But image seems to think that the lower left corner is (1,1). Can
someone suggest a way of persuading it to think otherwise. In effect,
I just want the y axis to run from from 1 to n downwards, not upwards.
I thought that something like axes=FALSE in

boxplots
Was there ever a convenient method provided to add boxplots to the current
plot at specified x values? There was a question by Martin Maechler some
time ago here, but I could seem to find any satisfactory resolution of it.
I see that there is an add=T option to boxplot and bxp, but I don't see
how to set the x-values.

s_copy
I'm trying to port some routines from S to R. The code includes some
fortran stuff that calls lapack. In the past in similar situations, but
without any lapack calls, I've had success using simply, as in the
V&R R-complements,
R SHLIB -o rq.so *.f

But now when the code is called from R, R crashes and I get a message

as.generic
I've been writing some matrix-type methods for a new class of sparse matrices
and for most methods this has been straightforward. However, there are
examples, like %*% and chol, that (apparently) R doesn't automatically
recognize as generic. What to do in these cases? At this point, I've
been writing new generic methods with slightly perturbed names %m% and

dyn.load and/or add new package (Windows 98)
Hi,
I have been trying to dyn.load a library (rq.obj), which will allow me to run
a quantile regression function, but so far unsuccessfully.
I have tried under windows 98 and R 6.24:
1) dyn.load("d:\\...\\rq.obj")
2) dyn.load("d:\...\rq.obj")
3) 1 and 2 accounting for case sensitivity.
4) dyn.load("d:/.../rq.obj")
5) Place the files in the directory where from I

quantreg 3.09
A new version of the quantile regression package (quantreg 3.09) is now
available on CRAN. The new features include:
1. a new fitting method "fnc" for rq() which allow the call to specify
linear inequality constraints on the coefficients.
2. an anova() function for rq objects that implements several F-like tests
for quantile regression models at a given quantile, and other F-like

solaris 64 build?
We have a solaris/sparc machine that has been running an old version
of R-devel: Version 2.2.0 Under development (unstable) (2005-06-04

faqs
An extremely modest proposal:
It would be nice if packages could have a FAQ and if
faq(package.name)
would produce this faq. And if, by default
faq()
FAQ()
would produce the admirable R faq... Apologies in advance
if there is already a mechanism like this, but help.search()
didn't reveal anything.

if the the print method didn't run them together. Could I make a plea
for
