make R package for windows on Linux
...bout building packages for windows
(e.g. mypkg.zip) seem to imply that the build be done on a windows machine.
Is there a simple way to make mypkg.zip under linux and then install it
as a zip file on a windows machine?
Sincerely,
Halldor

Windows plots & fontsize
...olution is to use par(ps=10), but I cannot find out how to
set this globally.
a) Does anyone know how I can set par(ps=10) by default on all figure?
b) Is there a windows specific way to set default fontsizes in figures?
Thanks,
Halld?r

A polar.plot BUG in plotrix 1.3.3 ?
...pos=c(0,90,180,270)*pi/180)
I have attatched the polar.plot function from the two different versions
of the package.
It seems that if not missing then label.pos is not changed at all in
version 1.3.3
So, a feature or a bug?
Sincerely,

printing ISO/8859-1 characters
...commandline a <-"??" works
ok, but print(a) or just:
a
returns the octal number.
However, when using THORN in plotlabels it works fine.
If anyone knows how to fix this I would be very happy to hear from them...
Thanks

Getting the character set
...uld find it in R
I could make good use of it.
In R both Sys.getlocale() and localeToCharset() can tell me which
charset I am using, but I haven't found a way to print out the
actual characters. Is there a way to do this?
Sincerely,
H.

locating intervals (corrected version)
..., but I suspect there
may be a faster and more elegant way to do this in R.
In Python (Numeric) the same can be achieved with
ix=Numeric.searchsorted(X[1:-1],Xi),
which is quite compact.
So, does anyone know of a corresponding R call that can achive the same?
Sincerely,
Halldór

How to know what device I am using
Some years ago I wrote a plotting routine that was run
on both Linux & Windows computers.
There were some differences in the way the plot looked
from the windows device and the X11 device.
To ensure consistency I used
getOption("device"))
and made some changes to the plotting if the windows device was being used.
Using this routine again, years later, I now notice that

bivariate linear interpolation
Hi,
I have three matrices (X,Y,P) with the same dimension. The X,Y grid is
regular and I want to
perform linear interpolation to pick out certain points. In matlab
appropriate call is
something like
Pout=interp2(X,Y,P,Xout,Yout, method="linear")
where Xout and Yout are the locations where I want the Pout data
(typically a different grid).
(Scipy has this routine in

read.table and variable length of tables
...0&STNM=04018",skip=10,nrows=97)
If I set nrows=98 I run into the trailing section.
>From day to day the table length changes. Is there a way to get read.table to always read in the correct
length and just stop when it hits the trailing section?
Sincerely,

problems with R-2.01 build with Mandrake 10.1
...n redhat. Are there any specific rpms that
need to be included before I can compile R so it includes X
I understand that Mandrake 10.1 uses Xorg instead of XFree86,
but am under the impression that these are compatible.
Sincerely,

image function with date-time on X axis
I am trying to plot a image where the x axis has the units of time.
When I issue the
image(x,y,z) command with x as a POSIXct object, it fails to put a
time stamp on the
x axis.
Instead I get a warning "Incompatible methods" warning and no dates on
my x axis.
This example shows my problem:
Rmat=t(matrix(data=rnorm(1:500),ncol=10,nrow=50))

Reasons to Use R
Dear All,
The institute I work for is organizing an internal workshop for High
Performance Computing (HPC).
I am planning to attend it and talk a bit about fluid dynamics, but
there is also quite a lot of interest devoted to data post-processing
and management of huge data sets.
A lot of people are interested in image processing/pattern recognition
and statistic applied to geography/ecology, but I
