R help - Jan 2006 - beginner Q: hashtable or dictionary?

Hi,

Is there something like a hashtable or (python)
dictionary in R/Splus?

(If not, is there a reason why it's not needed /
typical way to accomplish the same thing?)

Thank you

use a 'list':

> x <- list()
> x[['test']] <- 64
> x[['next one']] <- c(1,2,3,4)
> x
$test
[1] 64

$"next one"
[1] 1 2 3 4
> x[['test']]
[1] 64

Standard R vectors and list elements can given names, and can be accessed by
them.  This allows them to be used like the dictionaries or hashes of other
languages.

For example
>  x = c("a"=1, "b"=2, "c"=3)
>  x["a"]
a 
1 
> x["foo"] = "bar"
> x["foo"]
  foo 
"bar" 
> x
    a     b     c   foo 
  "1"   "2"   "3" "bar"
