Better to use an environment (and live with reference semantics)

Thanks gang,
I'll work with named vectors and concatenate as needed.
This might be ok for small problems, but concatenation is an inefficient
R pattern -- the objects being concatenated are copied in full, so
becomes longer, and the concatenation

Hi,
I was wondering if anyone has played around this this package called
rdict? It attempts to implement a hash table in R using skip lists. Just
came across it while trying to look for simpler text manipulation methods:

You can also use named vectors as something similar to
a python dictionary:
nvec = c('one'=20,'two'=30,'three'=40)
nvec['four'] = 50
nvec['one']
one
20
nvec['four']
four
50
Although the result is named, it can be used as a regular R
value:
20 + nvec['three']
three
60
