linkmapper: Point-and-Click Linkage Mapping and QTL Analysis

A 'shiny' application and a set of plain R functions for building genetic linkage maps and locating quantitative trait loci in F2 intercross, backcross and recombinant inbred line populations. It wraps 'onemap' (Margarido et al. 2007 doi:10.1111/j.2007.0018-0661.02000.x ) for segregation tests, two-point analysis, grouping, ordering and map estimation, and 'qtl' (Broman et al. 2003 doi:10.1093/bioinformatics/btg112 ) for interval mapping and composite interval mapping with permutation thresholds. Results can be exported as figures, tables, a self-contained HTML report and an R script that reproduces the analysis.
