wheat


       This data set gives the genetic marker information (DArT markers), phenotype, and the kinship matrix of a wheat breeding population.  The list wheat contains three elelments, 'y', 'marker' and 'A'.  The vector 'y' contains the phenotypic values for 282 wheat accessions, 'A' is a relationship (kinship) matrix of all the wheat accessions, and 'marker' is a 282 by 300 data frame for the genotype on 300 DArT markers for the wheat accessions.
     

datasets

This package implements the adaptive mixed lasso (AML) method proposed by Wang et al.(2011).  AML applies adaptive lasso penalty to a large number of predictors,  thus producing a sparse model, while accounting for the population structure in the linear mixed model framework.  The package here is primarily designed for application to genome wide association studies or genomic prediction in plant breeding populations, though it could be applied to other settings of linear mixed models.
