Re: [R] switching to Linux, suggestions?
I'm using SUSE with success on intel laptop and AMD desktop. You get the best of both worlds: rpm and source. I can easily get the rpm packages i need, and compile on my own the things that i can spend time on (such as R 2.0.1 -- compiles out of the box on suse). BTW, I'm looking to switch to Mac platform. Anyone had any experience with that?

I am trying to run R from an apache C++ module in a shell script to
plot some data to display it in apache later. I get the error
(reported in apache's logs):
Xlib: connection to :0.0 refused by server
Xlib: No protocol specified
Error in X11(paste(png::, filename, sep = ), width,
height, pointsize, :
unable to start device PNG
In addition: Warning message:
unable to open connection to X11 display`'
Execution halted
Is anyone familiar with this (i.e. running R from a non-X
environment)? Is there a way to get around this? I've seen some stuff
about virtual devices, but have no idea if it works or where to
start. If there is a simpler solution, please let me know.
-- doktora
I run the following shell script from the apache module using execve:
--
DISPLAY=:0.0
export DISPLAY
if $R --vanilla --quiet $rfile $log ; then
echo Success
else
echo There were errors in $0, see $log
fi
--
And $rfile contains this:
--
png(filename = /tmp/plot.png, width = 510, height = 360);
plot(some graph)
dev.off()

Re: [R] R 2.0.1 and RODBC install problem
Thank you for pointing me in the right direction. As I believe I had done my effort to find the answer prior to posting, and had a driver manager installed (unixODBC 2.2.8) and the database odbc drivers (psqlodbc 7.2.4). However, it might suffice to notice, for future reference (shall anyone encounter this problem), that the odbc driver manager needs to be installed with its development module. Mine wasn't and, consequently, didn't have the header files (sql.h and sqlext.h) installed. -- dok On Mon, 13 Dec 2004 19:24:16 + (GMT), Brian D Ripley [EMAIL PROTECTED] wrote: From the DESCRIPTION file: SystemRequirements: An ODBC driver manager and drivers.

I've used Xvfb in this situation. After installing Xvfb, you can do
something like this:
Xvfb :15
export DISPLAY=localhost:15
# Run R
FWIW, here's what I've used in the past for an Xvfb init script:
8
#!/bin/bash
#
# syslogStarts Xvfb.
#
#
# chkconfig: 2345 12 88
# description: Xvfb is a facility that applications requiring an X frame

# can use in place of actually running X on the server

[R] Moving standard deviation?
Is there a simple function in R to get a moving standard deviation (i.e. for the last x samples)? My goal is to plot bollinger bands around a moving average for price data.

Re: [R] Moving standard deviation?
I have tried there but didn't find anything useful. Most of the matches are for functions which take a std dev input, and the moving part of the query relates to something else (like moving average in the qcc package). Anyway, it's not too difficult to create the function, but I was wondering if anyone had done it before. Efficiency is a concideration, naturally. I'll post what i come up with... cheers dok On Mon, 13 Dec 2004 10:04:59 -0800, Spencer Graves [EMAIL PROTECTED] wrote: A search for moving standard deviation at www.r-project.org - search - R site search just produced 7 matches.

Re: [R] Calling R from a non-X shell script to plot?
So, it turns out that using Xvfb is quite simple and works great (fast). To summ up: if you are trying to plot a png file from a non-X environment, run Xvfb, like so (for example): Xvfb :9 -screen 0 800x600x16 This will run a virtual X server 9 with screen 0. In your shell script (or whatever other environment you are using), set the DISPLAY environment variable to :9.0: DISPLAY=:9.0 export DISPLAY presto -- dok On Mon, 13 Dec 2004 13:32:23 -0500, Rajarshi Guha [EMAIL PROTECTED] wrote: On Mon, 2004-12-13 at 12:25 -0500, doktora v wrote: I am trying to run R from an apache C++ module in a shell script to plot some data to display it in apache later.

So finally, i post to this list to see if anyouse else knows about this, or has done it!? Is it possible? Are there C++ or C R libraries?
