2019-08-09R-DEoptimR: initial commitbrook1-1/+2
Differential Evolution (DE) stochastic algorithms for global optimization of problems with and without constraints. The aim is to curate a collection of its state-of-the-art variants that (1) do not sacrifice simplicity of design, (2) are essentially tuning-free, and (3) can be efficiently implemented directly in the R language. Currently, it only provides an implementation of the 'jDE' algorithm by Brest et al. (2006) <doi:10.1109/TEVC.2006.872133>.
2019-08-09R-energy: initial commitbrook1-1/+2
E-statistics (energy) tests and statistics for multivariate and univariate inference, including distance correlation, one-sample, two-sample, and multi-sample tests for comparing multivariate distributions, are implemented. Measuring and testing multivariate independence based on distance correlation, partial distance correlation, multivariate goodness-of-fit tests, k-groups and hierarchical clustering based on energy distance, testing for multivariate normality, distance components (disco) for non-parametric analysis of structured data, and other energy statistics/methods are implemented.
2019-07-31R-zeallot: initial commit.brook1-1/+2
Provides a %<-% operator to perform multiple, unpacking, and destructuring assignment in R. The operator unpacks the right-hand side of an assignment into multiple values and assigns these values to variables on the left-hand side of the assignment.
2019-07-31R-vctrs: initial commit.brook1-1/+2
Defines new notions of prototype and size that are used to provide tools for consistent and well-founded type-coercion and size-recycling, and are in turn connected to ideas of type- and size-stability useful for analyzing function interfaces.

Tools to perform analyses and combine results from multiple-imputation datasets.
2019-07-31R-forcats: initial commit.brook1-1/+2
Helpers for reordering factor levels (including moving specified levels to front, ordering by first appearance, reversing, and randomly shuffling), and tools for modifying factor levels (including collapsing rare levels into other, 'anonymising', and manually 'recoding').
2019-07-31R-estimability: initial commit.brook1-1/+2
Provides tools for determining estimability of linear functions of regression coefficients, and 'epredict' methods that handle non-estimable cases correctly. Estimability theory is discussed in many linear-models textbooks including Chapter 3 of Monahan, JF (2008), "A Primer on Linear Models", Chapman and Hall (ISBN 978-1-4200-6201-4).
2019-07-31R-ellipsis: initial commit.brook1-1/+2
The ellipsis is a powerful tool for extending functions. Unfortunately this power comes at a cost: misspelled arguments will be silently ignored. The ellipsis package provides a collection of functions to catch problems and alert the user.
2019-07-31R-backports: initial commit.brook1-1/+2
Functions introduced or changed since R v3.0.0 are re-implemented in this package. The backports are conditionally exported in order to let R resolve the function name to either the implemented backport, or the respective base version, if available. Package developers can make use of new functions or arguments by selectively importing specific backports to support older installations.
2019-07-31R-acepack: initial commit.brook1-1/+2
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.
2019-07-31R-RcmdrMisc: initial commit.brook1-1/+2
Various statistical, graphics, and data-management functions used by the Rcmdr package in the R Commander GUI for R.
2019-07-31R-RandomFieldsUtils: initial commit.brook1-1/+2
Various utilities are provided that might be used in spatial statistics and elsewhere. It delivers a method for solving linear equations that checks the sparsity of the matrix before any algorithm is used. Furthermore, it includes the Struve functions.
2019-07-31R-Formula: initial commit.brook1-1/+2
Infrastructure for extended formulas with multiple parts on the right-hand side and/or multiple responses on the left-hand side (see <DOI:10.18637/jss.v034.i01>).

2019-06-15py-scipy12: added version 1.2.2adam1-1/+2
This is the last version that supports Python 2.7. Apparently, some packages still require Scipy with Python 2.7.
2019-06-15py-uncertainties: added version 3.1.1adam1-1/+2
uncertainties allows calculations such as (2 +/- 0.1)*2 = 4 +/- 0.2 to be performed transparently. Much more complex mathematical expressions involving numbers with uncertainties can also be evaluated directly. The uncertainties package takes the pain and complexity out of uncertainty calculations.

2018-09-17Add package R-RNetCDF version 1.9-1maya1-1/+2
An R interface to the NetCDF file format designed by Unidata for efficient storage of array-oriented scientific data and descriptions. The R interface is closely based on the C API of the NetCDF library, and it includes calendar conversions from the Unidata UDUNITS library. The current implementation supports all operations on NetCDF datasets in classic and 64-bit offset file formats, and NetCDF4-classic format is supported for reading and modification of existing files. From Kai-Uwe Eckhardt, updated as the previous distfile wasn't available. PR pkg/51607
