Re: [R] Making TIFF images with rtiff

When I open a DOS box and type gswin32c, I do indeed get an error message saying that it can't find the program.

Brant Inman - It needs to be in your Path. If you open up a DOS box and type gswin32c, I bet you get the same error message. You can fix this by editing the Path (via My Computer/Properties/Advanced/Environment variables, as you seem to know). If you use the R_GSCMD route, you may get in trouble with the embedded space in Program Files (dir/x c: will tell you the equivalent space-free name). Also, remember that environment changes do not affect running programs so you may need to exit R and restart. __ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.

Re: [R] LaTeX slide show (Was: Re: Taking code from packages)
Duncan,
it seems that you did not update 'xcolor' package properly. That's where
\rowcolors is defined. In some instances, especially under MikTeX, the
automatic update fails to update xcolor.sty. So, I suggest you download
the latest xcolor package from the same place as the beamer package and
then manually run 'latex xcolor.ins' to regenerate xcolor.sty. Then move
the *.def and *.sty file to the proper places to gain full compatibility.
Janusz.

What is the relevance of this? Also, your reference is useless to us,
which is important as this all hinges on your definitions.
The matrix created by the attached row and obtained using the following

that the real values are close, but not exactly so, and there is no
imaginary part whatsoever.

We don't have kinv.dat, but X is not circulant as usually defined.
Note that the eigenvectors are correct, and they are indeed real,
because X is symmetric.
Is this a bug in R? Any insight if not, please!
Well, first R calls LAPACK or EISPACK, so it would be a bug in one of
those. But in so far as I understand you, X is a real symmetric matrix,
and those have real eigenvalues and eigenvectors.
I think you are confused about the meaning of Toeplitz and circulant.
Compare
http://mathworld.wolfram.com/CirculantMatrix.html
http://mathworld.wolfram.com/ToeplitzMatrix.html
and note that ?toeplitz says it computes the *symmetric* Toeplitz matrix.
There is a very regretable tendency here for people to assume their
lack of understanding is `a bug in R'.

and sorted out the errors, then
R CMD build fBasics
Those same check logs show errors (like failure to build .dvi files).
Will it work if I download the Sources packages?

Re: Windows versus Unix packages in CRAN (Was Re: [R] Rmetrics)
Here is what I get:
R : Copyright 2004, The R Foundation for Statistical Computing
Version 1.9.0 (2004-04-12), ISBN 3-900051-00-3
.
[Previously saved workspace restored]

fLibraries: A SOFTWARE COLLECTION FOR FINANCIAL ENGINEERS
fBasics:Markets, Basic Statistics, Date and Time

(there were no alterations done to the above output except where
occurs!)
You simply need to remove the stuff related to MS Win from zzz.R;
in partricular the lines after if( ) to clear your message.
As you can see, the info relates to the WinMenu under MS Win.
Hope this helps.

Hello all:
On my linux platform, I ran the commands,
mkdir fBasics
unzip fBasics.zip -d fBasics
rm fBasics/src/*.o
R CMD check fBasics
That was 3 minutes. Next, I copied the files contained in
fBasics.Rcheck/fBasics to the R library.
library(fBasics)
fBasics:Markets, Basic Statistics, Date and TimeError in
try(winMenuAdd(Rmetrics)) : couldn't find function winMenuAdd
So, how do I get it to work with no problems in Linux??
Thanks,
Andrew

fBasics_190.10051.zip is a COMPILED version of the package, not
a source as you claim to be!
It works with no problems; well, at least under Linux.

Now me, I just did
unzip -a fBasics_190.10051.zip
R CMD INSTALL fBasics
rm -rf fBasics
in a naive and trusting manner. It took me considerably longer than 3
minutes to learn that this was what I should do, and when I did learn,
I wondered if it's this simple, why can't R CMD INSTALL do it?
Now I discover that it isn't that simple. The installation apparently
went smoothly. This is R, right? Never occurred to me that there might
be problems.
Now, B-G--R! It turns out that core stuff is supplied as .dll files,
which of course my UltraSPARC can do nothing with.
The author of the Rmetrics code has a perfect right to provide his code
in any form he wants under any conditions he wants (subject to GPL c).
In particular, if he wants to provide a distribution which only works under
Windows, that's perfectly OK.
**BUT** when a distribution is peculiar to one operating system, that really
should be highlighted in big bold letters: this is a WINDOWS BINARY
version, so that people who can't use Windows .DLL files are spared a day
of trying to figure out how to unpack and of doing an installation which
reports no errors at all and of them finding that things do not work.
There is *NOTHING* on http://www.itp.phys.ethz.ch/econophysics/R/download.htm
that says Windows only. Click on I acceptand the page you arrive at has
nothing in the text anywhere that says Windows only or what to do if not
Windows. (The http://.../R/bin/windows/contrib/1.9 address of the page
was, in retrospect, a big clue, sigh.)
It would of course be nice if the developers had done
R CMD check fBasics
But if you go into the Sources directory, which I suppose you must have,
for each of {fBasics,fExtremes,fOptions,fSeries} there is an
xxx-00check.log.txt, so they _did_ run R CMD check.
and sorted out the errors, then
R CMD build fBasics
Those same check logs show errors (like failure to build .dvi files).
Will it work if I download the Sources packages?

[R] Solaris 2.9
I've compiled the 1.8.0 R on Solaris 2.9 and when trying to use plot command I get the Bus error and a core dump. Anybody experienced something like this? If yes, what should I patch? Janusz.
