This package provides a general-purpose tool for dynamic report
generation in R, which can be used to deal with any type of (plain
text) files, including Sweave, HTML, Markdown, reStructuredText,
AsciiDoc, and Textile. R code is evaluated as if it were copied and
pasted in an R terminal thanks to the evaluate package (e.g., we do
not need to explicitly print() plots from ggplot2 or lattice). The
language in code chunks is not restricted to R (there is simple
support to Python and shell scripts, etc). Many features are borrowed
from or inspired by Sweave, cacheSweave, pgfSweave, brew and decumar.
The digest package provides a function 'digest()' for the creation of
hash digests of arbitrary R objects (using the md5, sha-1, sha-256 and
crc32 algorithms) permitting easy comparison of R language objects, as
well as a function 'hmac()' to create hash-based message
authentication code.
Markdown is a plain-text formatting syntax that can be converted to
XHTML or other formats. This package provides R bindings to the
Sundown markdown rendering library.
This package provides syntax highlighting for R source code. Currently
it supports LaTeX and HTML output. Source code of other languages can
be supported via Andre Simon's Highlight package.
This package provides a function tidy_source() to format R source
code. Spaces and indent will be added to the code automatically, and
comments will be preserved under certain conditions, so that R code
will be more human-readable and tidy. There is also a Shiny app as a
user interface in this package (see tidy_app()).
stringr is a set of simple wrappers that make R's string functions
more consistent, simpler and easier to use. It does this by ensuring
that: function and argument names (and positions) are consistent, all
functions deal with NA's and zero length character appropriately, and
the output data structures from each function matches the input data
structures of other functions.

In mathematics, a semigroup is an algebraic structure consisting of a set
together with an associative binary operation. A semigroup generalizes a
monoid in that there might not exist an identity element. It also
(originally) generalized a group (a monoid with all inverses) to a type
where every element did not have to have an inverse, thus the name
semigroup.
Some internal (non-API) routines to estimate the condition of
the basis matrix were added. These routines are mainly intended
to be used by the simplex-based solvers.
Two open modes "a" and "ab" were added to GLPK I/O routines.
Minor bug was fixed in the solver glpsol (command-line options
--btf, --cbg, and --cgr didn't work properly).
A serious bug was fixed in a basis factorization routine used
on the dense phase. (The bug might appear only if the number of
rows exceeded sqrt(2**31) ~= 46,340 and caused access violation
exception because of integer overflow.)
Two API routines glp_alloc and glp_realloc were documented.
Translation of the document "Modeling Language GNU MathProg"
to Spanish was included (in LaTeX and pdf formats).

2012-11-23 Kurt Hornik <Kurt.Hornik@wu.ac.at>
* DESCRIPTION (Version): New version is 1.2-33.
* src/char_date.c (char_date): Try avoiding buffer overflow as
suggested by Erik Doffagne <erik.doffagne@gmail.com>.
changelog:
0.3.3.0
* Add the isFloating or isInteger predicates.
Courtesy of Zejun Wu (@watashi).
* Add the toRealFloat' and toBoundedInteger functions.
Courtesy of Fujimura Daisuke (@fujimura).
0.3.2.2
* Enable package to link with integer-simple instead of
integer-gmp using the -finteger-simple cabal flag.
Courtesy of @k0ral.
0.3.2.1
* Parameterize inclusion of the Data.ByteString.Builder.Scientific
module using the bytestring-builder flag. Disabling this flag
allows building on GHC-7.0.4 which has bytestring-0.9 installed
by default.
0.3.2.0
* Add the floatingOrInteger function
* Fix build on GHC-7.0.4
* More efficient and better behaving magnitude computation
* Lower the number of cached magnitudes to 324 (same as GHC.Float)
0.3.1.0
* Don't normalize on construction but do it when pretty-printing
instead. Also provide a manual normalize function.
* Improve efficiency of toRealFloat
* Added note about caching magnitudes
* Dropped dependency on arithmoi
* Make benchmark easier to build
* Add junit XML output support (for Jenkins)
0.3.0.2
* Lower the minimal QuickCheck version.
* Make sure sized exponents are generated in the QuickCheck tests.
0.3.0.1
* Fix build for bytestring-0.10.0.*
0.3.0.0
* Fix a DoS vulnerability that allowed an attacker to crash the
process by sending a scientific with a huge exponent like
1e1000000000.
* Fix various RealFrac methods.
* Cache some powers of 10 to speed up the magnitude computation.
* Normalize scientific numbers on construction.
* Move the Text Builder to its own module &
provide a ByteString builder
* Added more documentation

This package contains code for generating high quality random numbers that
follow either a uniform or normal distribution. The generated numbers are
suitable for use in statistical applications.
The uniform PRNG uses Marsaglia's MWC256 (also known as MWC8222)
multiply-with-carry generator, which has a period of 2^8222 and fares well
in tests of randomness. It is also extremely fast, between 2 and 3 times
faster than the Mersenne Twister.
Compared to the mersenne-random package, this package has a more convenient
API, is faster, and supports more statistical distributions.
