You could use this:
source.and.set <- function(x) {
setwd(dirname(x))
source(x)
}
# use it like this:
source.and.set("/a/b/c.R")
or you could put this hack at the top of your source file in which
case whenever its source'd it will setwd to its directory:
this.dir <- dirname(parent.frame(2)$ofile)
setwd(this.dir)
