[R] [R-pkgs] hash-2.0.0

[Christopher Brown]

The hash-2.0.0 has been released to CRAN.

This package implements a data structure similar 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.

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)
  rm(h)


Warmest Regards,

Chris
