Path differences between Win XP, Win 7 & Linux

[Mark Knecht]

Hi,
I've worked on Win XP for a long time, and used R-gui over the last
year to learn the language a bit. Typically my R programs start off
with a block of code like this:

require(reshape)
require(TTR)
require(ggplot2)
require(chron)

### Requires MWKFunctions.R be loaded first
source("C:/Users/Mark/Documents/R/MWKFunctions/MWKFunctions.R")

Unfortunately Win XP and Win 7 use different user paths, and Linux
is different again:

source("C:/Users/Mark/Documents/R/MWKFunctions/MWKFunctions.R")
source("C:/Users/Mark/My Documents/R/MWKFunctions/MWKFunctions.R")
source("/home/mark/R/MWKFunctions/MWKFunctions.R")

Is there a better way to write this code so it works on all
platforms without changes?

Thanks,
Mark
