source problem
Thanks for the quick response! That's essentially how I was expecting to have to do it in the worst case. However, I was thinking that setting the chdir = TRUE should have taken care of this for me. Is this a bug? Or am I using it incorrectly? It seems like we shouldn't have to pass the paths around like that. John

I would sidestep the issue by using explicit paths at all times but keeping the directory roots in variables; e.g. firstPath <- "/usr/local/algo/R/script/f" secondPath <- "/home/john/R_script/" and then you can call things like source(paste(firstpath, "firstScript.r", sep="") This scheme does require the pathnames to be set when called. If you wanted your second script to run stand-alone you would have to put in a test such as if (!exists(secondPath)) secondPath <- "/home/john/R_script/" but I find it easier to define such things in .first or some other file I *always* source before working on the project. (Actually I create a list of them, which I call global.pathnames.) HTH

Hi,
I'm trying to call an R script from the command-line ("firstScript.r"
below). This script then sources another script in another directory
using the absolute path to the file
("/home/john/R_script/secondScript.r"). That script then needs to
source an R script in the same directory using a relative path
("thirdScript.r"). Neither script should know that it is being
sourced. For example,
/usr/local/algo/R/script/firstScript.r
/home/john/R_script/secondScript.r
/home/john/R_script/thirdScript.r
However, I am getting a message that this last file cannot be found.
I've changed the chdir and local attributes of source to TRUE and this
does not seem to change the behavior. Is there a way to do
this without
passing the absolute path to the R files around? Thanks for any help
you can offer.
John
