Interactive Maps for Data Exploration (Cartographer)
Cartographer provides interactive maps in R Markdown documents or at the R console. These maps are suitable for data exploration. This package is an R wrapper around Elijah Meeks’s d3-carto-map and d3.js, using htmlwidgets for R.

Continuous-Lag Spatial Markov Chains (spMC)
A set of functions is provided for
1) the stratum lengths analysis along a chosen direction,
2) fast estimation of continuous lag spatial Markov chains model parameters and probability computing (also for large data sets),
3) transition probability maps and transiograms drawing,
4) simulation methods for categorical random fields.

Regularized Generalized Linear Models with Interaction Effects (RAMP)
This package provides an efficient procedure for fitting the entire solution path for high-dimensional regularized generalized linear models with interactions effects under the strong heredity constraint.

Scores Features for Feature Selection (FeaLect)
For each feature, a score is computed that can be useful for feature selection. Several random subsets are sampled from the input data and for each random subset, various linear models are fitted using lars method. A score is assigned to each feature based on the tendency of LASSO in including that feature in the models. Finally, the average score and the models are returned as the output. The features with relatively low scores are recommended to be ignored because they can lead to overfitting of the model to the training data. Moreover, for each random subset, the best set of features in terms of global error is returned. They are useful for applying Bolasso, the alternative feature selection method that recommends the intersection of features subsets.

Create Cryptographic Hash Digests of R Objects (digest)
Implementation of a function ‘digest()’ for the creation of hash digests of arbitrary R objects (using the md5, sha-1, sha-256, crc32, xxhash and murmurhash algorithms) permitting easy comparison of R language objects, as well as a function ‘hmac()’ to create hash-based message authentication code. The md5 algorithm by Ron Rivest is specified in RFC 1321, the sha-1 and sha-256 algorithms are specified in FIPS-180-1 and FIPS-180-2, and the crc32 algorithm is described in For md5, sha-1, sha-256 and aes, this package uses small standalone implementations that were provided by Christophe Devine. For crc32, code from the zlib library is used. For sha-512, an implementation by Aaron D. Gifford is used. For xxHash, the implementation by Yann Collet is used. For murmurhash, an implementation by Shane Day is used. Please note that this package is not meant to be deployed for cryptographic purposes for which more comprehensive (and widely tested) libraries such as OpenSSL should be used.

Quantile Ordering (Quor)
Functions to compute confidence statistics for ordering population quantiles.
