Cross-compilers for 2.7.0
Hello,
Am I right in thinking the cross-compilations tools, kindly maintained
by Prof Ripley, are still waiting to be updated for 2.7.0?
Thanks,
Iago

setClass inside a function
Hello,
I would like to create a function that gets passed a class name and then calls setClass, and a few other functions, inside. I have done this in the past with setmethod, creating accessors for all slots in a set of S4 classes. But setClass is choking when my function is called isnide a package, telling about an error in exists(cname, where). I assume this to be a problem with the

lattice key inside panel
Hello,
I am trying to draw a key inside a single panel in a lattice xyplot. The
panel function uses panel.number() to use a slightly different style for
one of the panels. Once inside than panel I am using
draw.key(list(text=list(lab='catch'),
lines=list(lwd=c(2)),
text=list(lab='landings'),
rectangles=list(col=rgb(0.1, 0.1, 0, 0.1)),

Overloading S4 methods
Dear all,
I am experiencing some problems with S4 method overloading. I have
defined a generic for graphics:plot, using
setGeneric("plot", useAsDefault = plot)
and with
importFrom('graphics', 'plot') and
exportMethods('plot') in the NAMESPACE file of pkg A.
I then proceed to define a method for signature c('myS4class',
'missing'). This works

operators as S4 methods
Dear all,
I need to re-define some mathematical operators (+, *, /, etc) for an S4
class based on array. All references I have found (S Programming, Green
Book) show how to define S3 methods for this (like in page 89 of S
Programming for "-.polynomial"). What is the preferred S4 way for doing
this? I hope I haven't missed some obvious piece of documentation.
Many thanks,

Loading 'akward' data file
Generally you'd use file() to open the file, then use readLines(), say
inside a while() loop to read one `chunk' at a time. However, your example
looks a bit strange. The possibility of empty line makes it a bit more
complicated, by that last couple of lines seems to suggest that you could
have a line of data follow by another line of data without variable label.
If that's true, I

Error in ?lowess
The lowess() help page refers to documentation in "src/appl/lowess.doc".
This was moved to "src/library/stats/src/lowess.doc" in 2007. This

Please make lowess() generic (was: Reorganization of packages in the R distribution)
As I've mentioned a number of times. I find it very useful to have lowess()
become a generic function so that a lowess.formula() can be defined.
Below is a patch that makes both changes, as well as updating the
corresponding help documentation.

lines(lowess()) trouble
hi: apologies for taking up everyone's time. my problem is probably
documented somewhere, but I again cannot find it. (which reminds me: I cannot
find a search engine that allows me to search the archives of this very useful
mailing list.)

what does it do at the x-min and x-max of a data set?) Rather than

A Question on lowess() function
Hi, all,
I want to use lowess(x, y) where x and y are vectors of length of 4000+. In
fact, x and y are log of some vectors. So, some of the elements are NaN.
lowess() can not take away those elements then do the fitting. It will give
the error message and do nothing.
1. Can anybody tell me how to get rid of those NaN's and use lowess()?
2. How to get the LOWESS fitting values for any

95% CI bands on a Lowess smoother
Hi there,
I'm plotting some glass RI values just by plotting
plot(x)
then I put on my lowess smoother
lines(lowess(x))
now I want to put on some 95% Confidence Interval bands of the lowess
smoother, but don't know how??
Thanks

DLLs adding in C++ code
I would like to utilise the power of R by adding my own software as a
package written in C++. As a first step I am trying
to write a DLL with a simple function that can be called from R. The DLL
contains a C++ routine written and complied in Microsoft Visual C++ Ver 6.0
and is based upon the example in R-Exts
eg I am trying to create the following example function

mcmc
Hello,
I am about to move all of my modelling work into R, and I have been
investigating the present state of MCMC and Bayesian methods in R.
Following a thread on the mailing list in 2000, I have looked at
mcmcpack and Hydra. Three years down the line, is there anything new in
this area? I have used both MCSim and WinBUGS in the past. The first one
seems promising, but is too focused towards

Cross build Makefile

versions of R packages in Linux with R 1.9.0. When compiling R with the

If I fiddle a bit with it later on I also get errors about log1p bein

lowess() as a generic function
Hi All,
I've been providing a generic version of lowess() in my 'gregmisc' library,
along with a 'lowess.formula' and 'lowess.default'.
Can/should these be moved into base?
