[R] Directory-like data organisation w/ environments?

[Liaw, Andy]

Would attaching a nested list be close to what you want?  E.g.,

> x <- list(y1 = list(z = matrix(1:4, 2, 2)), y2=matrix(0, 3, 2))
> attach(x)
> y2
     [,1] [,2]
[1,]    0    0
[2,]    0    0
[3,]    0    0
> attach(y1)
> z
     [,1] [,2]
[1,]    1    3
[2,]    2    4

You should be aware that the global environment is #1 on the search list,
and you can't attach anything else at position 1.  So if you have something
in the workspace that has the same name as in what you attach()'ed, the one
in the workspace is seen.

HTH,
Andy
