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

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,
Iago

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

Smallest R executable
Hello,
I am trying to find out how can I generate the smallest R executable. R is to be run in a grid application, in batch mode, so I need a small exceutable, possibly getting rid of any interactive component. Should I look at the embedded version? Any other pointers?
Many thanks,

S4 generic for lowess
Hi,
A lowess method is defined in our package for one of our S4 classes. To
explicitely define the generic this is being used
if (!isGeneric("lowess"))
setGeneric("lowess", useAsDefault = lowess)
This works fine for many other methods inherited from various R
packages. In this case a warning is issued in R CMD check:

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

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

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

Bundle internal dependencies
Dear all,
When creating a bundle with some internal dependencies (package B in
bundle depends on package A), would having the same version installed
suffice? Can I ignore the dependencie in package B's description? The
test of package B fails when calling data() for an object in pacakge A,
so I am not sure right now whether the whole dependencie is not being
met or simple relates to data().

lattice key inside panel

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

SHLIB steps on a Makefile
Hi,
I need to create a Makefile.win for a given package so as to fiddle
slightly with the compilation process. My Makefile works fine in Linux
but I am having trouble creating Makefile.win for MinGW. I first
looked at the commands that Rcmd SHLIB appeared to be running and
copied those onto the Makefile. But one step seems to be missing, the
creation of the _res.rc file needed by windres

Cross build Makefile
Hello,
I am trying to use Yan and Rossini's Makefile for cross building Windows
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

glm with four variables
Hi,
Sorry if this is a very basic question, but when I run this
glm(formula = loge ~ lat + ne + dep, family = gaussian)
summary shows the same formula but results only for the first two variables.
What am I doing wrong?

Need for garbage collection after creating object
Hello,
After experiencing some difficulties with large arrays, I was surprised
to see the apparent need for class to gc() after creating fairly large
arrays. For example, calling
a<-array(2, dim=c(10,10,10,10,10,100))
makes the memory usage of a fresh session of R jump from 13.8 Mb to
166.4 Mb. A call to gc() brought it down to 90.8 Mb,
