Package: r-cran-qtl (1.05-2-1)

GNU R package for genetic marker linkage analysis

R/qtl is an extensible, interactive environment for mapping quantitative trait loci (QTLs) in experimental crosses. It is implemented as an add-on-package for the freely available and widely used statistical language/software R (see http://www.r-project.org). The user will benefit from the seamless integration of the QTL mapping software into a general statistical analysis program.

The current version of R/qtl includes facilities for estimating genetic maps, identifying genotyping errors, and performing single-QTL genome scans and two-QTL, two-dimensional genome scans, by interval mapping (with EM algorithm), Haley-Knott regression, and multiple imputation. All of this may be done in the presence of covariates (such as sex, age or treatment). The fit of higher-order QTL models, with sophisticated techniques for model comparisons and model search, will be incorporated soon.
