So if I have the R function foo and I have my main method in Java how would I
call the method foo? What would be the syntax?: Do I create an REengine
first?
public static void main(String[] args)
{
}

Nevermind about the previous post. However, I in the retest sample code, I
can run my own function in the command line. But, say I am creating a GUI
and I want the user to enter the model parameters. How do I, within the java
code, explicity call my unique function without going to the console?
I guess the best answer to your question depends on the specifics of the
implementation, but, i think if I were in your situation and I wanted to be
able to call a function "foo" found in file "foo.R" every time a user
clicked a button, i'd just
source("path to "foo.R")
which just parses the
So I copy and pasted my function to the R startup file. However, in my
function, I change directories. When I run the function in Eclipse, I get a
message in the console, "Cannot change working directory". Why is this?

Sure, so, all I was saying about gedit is that it handles the R session for
me, which is a neat feature but not mandatory to get the expected result,
there's an rprofile.site file which describes your (user specific)
preferences,
you can manually edit this file to add functions at start up by d
I am still a little unsure of how I would do this. I do not want to install
GEdit. Is there anyway in the retest in the included example that you can
show me how I would do this? My function is:
lol = function(x,y)
{
sum = x+y
mod = sum %5
return mod
}

I think the basic answer here is "package it", which I did a couple of times
but found inconvenient if I was going to change the function fairly often,
i've taken a different tact, just including custom functions when R starts,
i wrote a function that runs when I start the R session, loading the
