I *strongly* suggest you consider packages if you are sharing collections of
R functions and scripts with other people. Compared to other programming
languages I have used, R makes it dead simple to create packages. All you
really need to get started is:
?package.skeleton()
That command creates a set of folders whose structure is pretty self
explanatory:
package.skeleton( 'myPackage' )
Creates the beginnings of a package structure:
myPackage/
R/ => Files containing your custom R functions go in here
data/ => Data sets go in here
man/ => For documentation files
inst/ => Everything else such as scripts and config files
The "Writing R Extensions Manual" can help you fill in the rest of the
blanks.
The bottom line is that creating a package cost a minimal investment of
extra time and pays back huge dividends if the collection of scripts and
data files you are sharing gets complex or you people ask you to document
the software that they are starting to depend on.

Great, this is the solution. It works if the script has been saved

The best recipie I have for dealing with this situation is:
1. Place R scripts in a package (a very good idea anyway if you are
distributing code to others).
2. Place a configuration file in the package that contains info such as
paths to data directories.
3. Customize the configuration file after installing the package (if
necessary).
Then your script accesses the configuration file, which is in a known fixed
location, and uses the information inside to find other files that may be in
unknown and changing locations.
You could also place the configuration file in a location such as:
~/.MyPackageConf
Since:
path.expand( '~/' )
Has a pretty predictable behavior across platforms. This would save it from
being overwritten every time you updated the package.
Hope this helps!

I also was about to suggest putting the code in a package because then
you have system.file available, which I presume works across platforms:
> system.file("RunTests.R",package="DistributionUtils")
[1] "/usr/local/david/R/DistributionUtils"
> system.file("unitTests/runTests.R",package="DistributionUtils")
[1] "/usr/local/david/R/DistributionUtils/unitTests/runTests.R"
Sorry, I copied that incorrectly. Should be:
> system.file(package="DistributionUtils")
[1] "/usr/local/david/R/DistributionUtils"
> system.file("unitTests/runTests.R",package="DistributionUtils")
[1] "/usr/local/david/R/DistributionUtils/unitTests/runTests.R"

Re: [R] Path to R script
Don't quite understand your question, but it looks like a more IT issue to me. I guess you store your R scripts in a central location (e.g. a server) and everybody call them from their own workstation, right? Or you can always bundle your R scripts into a package and distribute it around your group. ...Tao - Original Message > From: Johannes W.
