#---------------------------------------------------------------------------# #INVERSE ADDITIVE PEDIGREE RELATEDNESS MATRICES inversepedigree1.RData and inversepedigree2.RData are R data files which contain the sparse inverse pedigree relatedness matrices for pedigree 1 and pedigree 2 respectively. These files have been created from the raw pedigrees using in the asreml.Ainverse command in ASREML-R. Data structure: data frame with 3 columns holding the lower triangle of the inverse relationship matrix in sparse form. The first 2 columns are the row and column indices of the matrix elements, and the third column holds the (inverse) matrix element itself. Sort order is columns within rows, that is, the lower triangle row-wise. Each data frame has an attribute "rowNames" containing the vector of identifiers for the rows matrix.
