R language packages for Anaconda
================================

   :depth: 1

The R language packages available for install from conda are available at
http://repo.continuum.io/pkgs/r/ . You can install any of these R language
packages into your current environment with the conda
command ``conda install -c r package-name``. NOTE: Replace ``package-name``
with the name of the package. For example, you can install the package
``r-acepack`` with the command ``conda install -c r r-acepack``.

TIP: You can also search for any R package if you know the name,
such as ``conda search -f EXACTNAME``. Replace ``EXACTNAME`` with the
desired R package name.

Many Comprehensive R Archive Network (CRAN) packages have been been rebuilt and
made available as conda packages. Anaconda does not provide builds of the
entire CRAN repository, so there are some packages in CRAN that are not
available as conda packages.


R Essentials bundle
===================

Rather than install each R language package individually, you can get
the R Essentials bundle. It includes about 100 of the most popular
scientific packages for the R programming language.

You can install the R Essentials bundle with this command::

    conda install -c r r-essentials

      <td>Two nonparametric methods for multiple regression transform selection are provided. The first, Alternative Conditional Expectations (ACE),  is an algorithm to find the fixed point of maximal correlation, i.e. it finds a set of transformed response variables that maximizes R^2 using smoothing functions [see Breiman, L., and J.H. Friedman. 1985. "Estimating Optimal Transformations for Multiple Regression and Correlation". Journal of the American Statistical Association. 80:580-598. <doi:10.1080/01621459.1985.10478157>]. Also included is the Additivity Variance Stabilization (AVAS) method which works better than ACE when correlation is low [see Tibshirani, R.. 1986. "Estimating Transformations for Regression via Additivity and Variance Stabilization". Journal of the American Statistical Association. 83:394-405.  <doi:10.1080/01621459.1988.10478610>]. A good introduction to these two methods is in chapter 16 of Frank Harrel's "Regression Modeling Strategies" in the Springer Series in Statistics.</td>

      <td>1.1_12</td>
      <td>bitmapped vectors of booleans (no NAs),  coercion from and to logicals, integers and integer subscripts;  fast boolean operators and fast summary statistics.  With 'bit' vectors you can store true binary booleans {FALSE,TRUE} at the  expense of 1 bit only, on a 32 bit architecture this means factor 32 less  RAM and ~ factor 32 more speed on boolean operations. Due to overhead of  R calls, actual speed gain depends on the size of the vector: expect gains  for vectors of size > 10000 elements. Even for one-time boolean operations  it can pay-off to convert to bit, the pay-off is obvious, when such  components are used more than once.  Reading from and writing to bit is approximately as fast as accessing  standard logicals - mostly due to R's time for memory allocation. The package  allows to work with pre-allocated memory for return values by calling .Call()  directly: when evaluating the speed of C-access with pre-allocated vector  memory, coping from bit to logical requires only 70% of the time for copying  from logical to logical; and copying from logical to bit comes at a  performance penalty of 150%. the package now contains further classes for  representing logical selections: 'bitwhich' for very skewed selections and  'ri' for selecting ranges of values for chunked processing. All three index  classes can be used for subsetting 'ff' objects (ff-2.1-0 and higher).</td>

Fitting takes place by fitting generalized linear models on iteratively updated pseudo-data. The interface is essentially the same as 'glm'.

Curves from different cross-validation or bootstrapping runs can be averaged by different methods, and standard deviations, standard errors or box plots can be used to visualize the variability across the runs. The parameterization can be visualized by printing cutoff values at the corresponding curve positions, or by coloring the curve according to cutoff. All components of a performance plot can be quickly adjusted using a flexible parameter dispatching mechanism. Despite its flexibility, ROCR is easy to use, with only three commands and reasonable default values for all optional parameters.</td>

Currently only fixed-effects models are implemented, i.e., no random-effects models. Many (150+) models and distributions are estimated by maximum likelihood estimation (MLE) or penalized MLE, using Fisher scoring. VGLMs can be loosely thought of as multivariate GLMs. VGAMs are data-driven VGLMs (i.e., with smoothing). The other classes are RR-VGLMs (reduced-rank VGLMs), quadratic RR-VGLMs, reduced-rank VGAMs, RCIMs (row-column interaction models)---these classes perform constrained and unconstrained quadratic ordination (CQO/UQO) models in ecology, as well as constrained additive ordination (CAO).
