S4 Inheritance of environments
...gt; slotNames(inEnv) # ".xData"
[1] ".xData"
> inherits(inEnv, 'environment' ) # TRUE
[1] TRUE
My questions is whether this behavior is a bug? By design? A work
around? Etc.?
Thanks kindly for your reply,

hash-2.0.0
...ilar to hashes in Perl and
dictionaries in Python but with a purposefully R flavor. For objects of
appreciable size, access using hashes outperforms native named lists and
vectors.
This version accounts for changes in R-2.11.0 and is optimized for both
speed and usabiity.
Some references:
http://opendatagroup.com/2010/04/26/hash-2-0-0/
http://opendatagroup.com/2009/07/26/hash-package-for-r/
Basic Examples:
h <- hash( keys=letters, values=1:26 )
h <- hash( letters, 1:26 )
h$a # 1
h$foo <- "bar"
h[ "foo" ]
h[[ "foo" ]]
clear(h)

list comprehension to create an arbitrary-sized list with arbitrary names/values
In python, one can do this
mydict = dict([(keyfun(x), valfun(x)) for x in mylist])
to create a dictionary with whatever keys and values we want from an
input list of arbitrary size. In R, I want to similarly create a list
with names/values that are generated by some keyfun and valfun
(assuming that keyfun is guaranteed to return something suitable as a
name). How can I do this?

Hello world:
Has anyone used hex notation within R to represents integers?
Cheers,
