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...

MAPfastR: QTL mapping in outbred line crosses

MAPfastR is an R package for mapping quantitative trait loci (QTL) in outbred line crosses. It contains all the functions required to perform a QTL analysis in outbred lines. Some of the functions implement different algorithms that can be used interchangeably and it is up to the user to decide which will be applied. This gives the user a certain degree of flexibility when constructing the anal...

R/qtl: QTL Mapping in Experimental Crosses

SUMMARY R/qtl is an extensible, interactive environment for mapping quantitative trait loci (QTLs) in experimental populations derived from inbred lines. It is implemented as an add-on package for the freely-available statistical software, R, and includes functions for estimating genetic maps, identifying genotyping errors, and performing single-QTL and two-dimensional, two-QTL genome scans by ...
