PrevMap: An R Package for Prevalence Mapping

vqtl: An R package for Mean-Variance QTL Mapping

Most existing methods for QTL mapping in experimental crosses assume that the residual variance is constant across all individuals. But common situations violate this assumption. For many phenotypes, one sex is more variable than the other, some experimenters make more precise measurements than others, and specific genetic factors influence environmental sensitivity. In these cases, mean-varian...

An R package with BridgeDb for identifier mapping

An R package for state-trace analysis.

State-trace analysis (Bamber, Journal of Mathematical Psychology, 19, 137-181, 1979) is a graphical analysis that can determine whether one or more than one latent variable mediates an apparent dissociation between the effects of two experimental manipulations. State-trace analysis makes only ordinal assumptions and so, is not confounded by range effects that plague alternative methods, especia...

RFreak–An R Package for Evolutionary Computation

RFreak is an R package providing a framework for evolutionary computation. By enwrapping the functionality of an evolutionary algorithm kit written in Java, it offers an easy way to do evolutionary computation in R. In addition, application examples where an evolutionary approach is promising in computational statistics are included and described in this paper. The package is thus further suppo...

fitdistrplus: An R Package for Fitting Distributions

The package fitdistrplus provides functions for fitting univariate distributions to different types of data (continuous censored or non-censored data and discrete data) and allowing different estimation methods (maximum likelihood, moment matching, quantile matching and maximum goodness-of-fit estimation). Outputs of fitdist and fitdistcens functions are S3 objects, for which kind generic metho...
