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 slowe
Thanks gang,
I'll work with named vectors and concatenate as needed.

Paul -
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
If t
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:
