Cairo also has full transparency support, both for png and pdf.

Ulrik, I presume the problem you ran into was the absence of the cairo 
library dependency:

configure: error: Cannot find cairo.h! Please install cairo 
(http://www.cairographics.org/) and/or set CAIRO_CFLAGS/LIBS 
correspondingly.

which has it's own library dependencies as well. Most all Linux 
distributions (I'm presuming you're running Linux) have ways to install 
these dependencies easily: apt-get, rpm, etc.

Otherwise, if you had other problems installing Cairo, please let me 
know and I can fix them.

 The png() device requires an X server for the image rendering. You might
 be able to get away with exporting the DISPLAY environment variable

 export DISPLAY=:0.0 # try and connect to X server on display 0.0

 within your script, but it will only work if the script is executed by
 the same user as is running the X server, *and* the X server is running
 at the time the script is executed.

 There are a handful of packages that will create a png without the
 presence of an X server, and I'm partial to Cairo (since I've done some
 work on it). You can install the latest version like this:

 install.packages("Cairo",,'http://rforge.net/',type='source')

 Cairo can also outputs nice pdf's with embedded fonts... useful if you
 want to embed high-quality OpenType or TrueType fonts.

 Best,

 Jeff

You cannot do transparency via postscript.

I would suggest using pdf() and converting the output of that, which often 
works even better (and does have full transparency support).

As there are two separate versions of png() for different OSes, comments 
like that are very system-dependent.  Other postings suggest this is 
Windows, and if png() is giving poor results there it suggests a problem 
with the way Windows' GDI is configured (which depends on the graphics 
card).

And of course, PNGs don't 'look' at all: they are rendered by some other 
tool, and quite often the perceived problem with R graphical output is in 
fact with the rendering tool.

Or see png2() in R.utils, which imitates png() but uses bitmap(),
which in turn uses postscript-to-png via ghostscript.  BTW, personally
I think PNGs generated via bitmap() look way better than the ones
generated via png().

The png() device requires an X server for the image rendering. You might 
be able to get away with exporting the DISPLAY environment variable

export DISPLAY=:0.0 # try and connect to X server on display 0.0

within your script, but it will only work if the script is executed by 
the same user as is running the X server, *and* the X server is running 
at the time the script is executed.

There are a handful of packages that will create a png without the 
presence of an X server, and I'm partial to Cairo (since I've done some 
work on it). You can install the latest version like this:

install.packages("Cairo",,'http://rforge.net/',type='source')

Cairo can also outputs nice pdf's with embedded fonts... useful if you 
want to embed high-quality OpenType or TrueType fonts.

[R] Runing R in a bash script

2007-04-17 Thread Ulrik Stervbo
Hello!

I am having issues trying to plot to a ong (or jpg)  when the R-code in a
bash script is executed from cron.

I can generate a pdf file, but when I try to write to a png, the file is
created, but nothing is written. If I execute the bash script from my
console, everything works file. Any ideas?

In my cron I have SHELL=/bin/bash - otherwise /bin/shell is used and the
folowing enery, so example is executed every minute
* * * * * [path]/example.sh

I am running
R version 2.4.1 (2006-12-18)

Here's a minimal example - two files one R-script ('example.r') and one
bash-script ('example.sh')

example.r
# Example R-script
x <- c(1:10)
y <- x^2
png(file="example2.png")
#pdf(file="example2.pdf")
plot(x,y)
graphics.off()

example.sh
#/bin/bash
#
# Hello world is written to exhotext every time cron executes this script
echo "Hello world" > echotext
# This works, but not when executed from cron
n=`R --save < example.r`
# using exec as in `exec R --save < example.r` dosent work with cron either
# This also works, but nothing is written to the png when executed from cron
R --save
