TSDFGS: Training Set Determination for Genomic Selection

Finds a training set for genomic selection and the size it needs. The r-score of Ou and Liao (2019) <doi:10.1007/s00122-019-03387-0> is derived from Pearson's correlation between the genomic estimated breeding values and the phenotypic values of the test set. optTrain() searches for a good training set, and SSDFGS() searches for its size. Eighteen criteria are available to score or optimize a training set, among them A-, D-, E- and G-optimality, PEVmax, MSPE, CDmean, CDmax, and genomic relationship criteria (Chen et al. (2024) <doi:10.1007/s00122-024-04766-y>; Fernandez-Gonzalez et al. (2023) <doi:10.1007/s00122-023-04265-6>). The computation uses 'Rcpp' and 'RcppEigen', and independent searches can run on several threads with 'OpenMP'.
