[R] attaching directories in R?

[Agustin Lobo]

Hi!

I'm trying to use R. In S+ I use to have different projects
in different directories. To make
the functions and other objects 
from a directory available
and to use that directory as default,
I just do:

attach(directory, pos = 1)

where directory is, for example,

"/home/alobo/S/bolivia1"

Acutually, I have a simpe function
(work) to do this:

> work
function(directorio)
{
	if(any(search() == directorio))

		detach(what = directorio)

	attach(directorio, pos = 1)

	options(prompt = paste("Splus/", paste(directorio, ">", sep = ""), 
sep = ""))

	search()
}

And I have a simpe function for each directory, i.e.,
for directory $home/Sutil

> util

function()
{

	work(paste(home, "/Sutil", sep = ""))
}


Now, if I try to do the same in R, I get:

> util()
Error: attach only works for lists and data frames

How could I do the equivalent function in R?


Thanks
