\title{Ridge regression and other kernels for genomic selection}
\description{This package has been developed primarily for genomic prediction with mixed models (but it can also do genome-wide association mapping with \code{\link{GWAS}}). The heart of the package is the function \code{\link{mixed.solve}}, which is a general-purpose solver for mixed models with a single variance component other than the error. Genomic predictions can be made by estimating marker effects (RR-BLUP) or by estimating line effects (G-BLUP). In Endelman (2011) I made the poor choice of using the letter G to denotype the genotype or marker data. To be consistent with Endelman (2011) I have retained this notation in \code{\link{kinship.BLUP}}. However, that function has now been superseded by \code{\link{kin.blup}} and \code{\link{A.mat}}, the latter being a utility for estimating the additive relationship matrix (A) from markers. In these newer functions I adopt the usual convention that G is the genetic covariance (not the marker data), which is also consistent with the notation in Endelman and Jannink (2012).
