[R] beginner Q: hashtable or dictionary?

[Christos Hatzis]

I was wondering if there is an easy way to extend this to implement a 2-D
hash, i.e. 2-way indexing? 

> x[["a"]][["b"]] <- "something"

Thanks.

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
