Quantitative Trait Locus Mapping in Experimental Crosses.
R/qtl2
R/qtl2 (aka qtl2) is a reimplementation of the QTL analysis software R/qtl, to better handle high-dimensional data and complex cross designs.
Also see the related packages, qtl2convert (for converting data among the R/qtl2, DOQTL, and R/qtl formats), qtl2fst (for storing genotype probabilities on disk), and qtl2ggplot (for ggplot2-based data visualizations).
Installation
Install R/qtl2 from CRAN:
install.packages("qtl2")
