rfPermute

cran
87th

Percentile

Estimate significance of importance metrics for a Random Forest model by permuting the response variable. Produces null distribution of importance metrics for each predictor variable and p-value of observed. Provides summary and visualization functions for 'randomForest' results.

sprex

cran
86th

Percentile

Calculate species richness functions for rarefaction and extrapolation.

swfscMisc

cran
79th

Percentile

Collection of conversion, analytical, geodesic, mapping, and plotting functions. Used to support packages and code written by researchers at the Southwest Fisheries Science Center of the National Oceanic and Atmospheric Administration.

strataG

cran
68th

Percentile

A toolkit for analyzing stratified population genetic data. Functions are provided for summarizing and checking loci (haploid, diploid, and polyploid), single stranded DNA sequences, calculating most population subdivision metrics, and running external programs such as structure and fastsimcoal. The package is further described in Archer et al (2016) <doi:10.1111/1755-0998.12559>.

banter

cran
53th

Percentile

Create a hierarchical acoustic event species classifier out of multiple call type detectors as described in Rankin et al (2017) <doi:10.1111/mms.12381>.

maptools

cran
99th

Percentile

Set of tools for manipulating geographic data. It includes binary access to 'GSHHG' shoreline files. The package also provides interface wrappers for exchanging spatial objects with packages such as 'PBSmapping', 'spatstat', 'maps', 'RArcInfo', and others.

apex

cran
86th

Percentile

Toolkit for the analysis of multiple gene data. Apex implements the new S4 classes 'multidna', 'multiphyDat' and associated methods to handle aligned DNA sequences from multiple genes.

skeleSim

cran
77th

Percentile

A shiny interface and supporting tools to guide users in choosing appropriate simulations, setting parameters, calculating summary genetic statistics, and organizing data output, all within the R environment. In addition to supporting existing forward and reverse-time simulators, new simulators can be integrated into the environment relatively easily.
