In (approximately) reverse chronological order:
- Rcpp
- An R interface to
C++. Initially written by Dominick Samperi, now maintained by Dirk
Eddelbuettel. Releases are provided via CRAN and code is hosted on
R-Forge.
- RPostgreSQL
- An R interface to
PostgreSQL.
Written by Sameer Kumar Prayaga during the summer of 2008
as part of the Google Summer of Code 2008 program. Dirk Eddelbuettel had
suggested the topic, acted as mentor and currently coordinates releases.
- littler
- (Written with Jeffrey Horner) A scripting front-end for GNU R to write simple
'shebang'-line scripts, or quick command-line expressions. Available
here, at Vanderbilt's
BioStat wiki and the Googlecode
SVN.
- random
- A GNU R package to
access true (i.e. non-deterministic) random numbers from random.org. Available
here and via all CRAN mirrors.
- digest
- A GNU R package to
create `hash' digests of arbitrary R objects using the md5, sha-1 and
crc32 algorithms permitting easy comparison of R objects. Available
here and via all CRAN mirrors.
- Quantian
- A directly bootable and self-configuring Linux system on a
single dvd. Quantian is an extension of
Knoppix
from which it takes its base system of about 2.0 gigabytes of
software, along with automatic hardware detection and configuration.
To this, Quantian adds about 5.5 gigabytes of scientific / mathematical software
such as
R,
Octave,
GSL,
Maxima or
QuantLib.
- RQuantLib
- A GNU R package to
interface with the QuantLib
library.
GNU R is `GNU S' - A language
and environment for statistical computing and graphics.
QuantLib is a free/open-source
library and framework for quantitative finance, financial
engineering, modeling, trading, and risk management. Available
here and via all CRAN and Debian mirrors.
- BeanCounter
- A Perl stock portfolio performance toolkit providing functions to
download, store (in an SQL database) and analyse stock market data in a
convenient and efficient way. Available here and via all CPAN and Debian mirrors.
- SMTM aka Show Me The Money
- A highly configurable Perl/Tk stock ticker and performance display
for stocks from around the globe. Available here and via all CPAN and Debian mirrors.
- Finance::YahooQuote
- A Perl module to download stock (and other) quotes from
Yahoo! Finance. Originally
written by Dj Padzensky; mainted by me since 2002. Available here and
via all CPAN and Debian mirrors.
- Mersenne Twister RNG for GNU
Octave
- C++ code for another (extremely fast
yet excellent statistical properties) RNG for GNU Octave using Shawn Cokus'
implementation of the Mersenne Twister
MT19937.
Note that this has been integrated, in a more polished rewrite by
Paul Kienzle, into Octave-Forge.
- PostgreSQL modules for GNU
Octave
- C++ code to interface a Postgres SQL database directly
from GNU Octave.
- Also see my Debian GNU/Linux page
with information about the few dozen packages I maintain.
