Folks,

A small group of us are working together to develop a set of R functions 
to support data management and analysis using Eclipse/StatET in a Windows 
environment.  We are using Git/EGit for version control. We work within 
our own repository and occasionally push to a common remote location.

I'd like to have the code source files from the 'local' git repository 
without modification, where 'local' could mean c:\yada\ for one person, 
m:\my documents\wetlands\ for another, and l:\foo\bar\sharedRemote\wet\ to 
another user.

The chdir argument to source() has been suggested for similar questions, 
but I have not been able to figure out how this helps without hardcoding 
the location in some manner.

One option is for each repository to have an untracked file which sets the 
local working directory before sourcing another file that actually sources 
the function definitions.  This file (projectStart.r below) would be read 
into the R session prior to use, at least during development.

projectStart.r                  # untracked
    setwd("c:\yada\")           # or setwd("L:\foo\bar\sharedRemote\wet\") 
-- this is the only difference among repository locations.
    source("projectStart2.r")

projectStart2.r                 # tracked
    source("func1.r")
    source("func2.r")
    source("func3.r")
    ...

func1.r                         # tracked

func2.r                         # tracked

func3.r                         # tracked

...

Is there an easier or better accepted method?

Thank you for your time,
cur
