geno: Genotype-environment data set with missing values

Description

A data-frame with 16 rows corresponding to genotypes (triticale lines) and 10 columns corresponding to different environments where the genotypes were sown. Each cell of the data-frame corresponds to the grain yield (kilograms per hectare) for one genotype in an environment. The first six genotypes correspond to the so-called ``complete'' type, while the next eight were of the ``substituted'' type and two check genotypes were included. Such data sets are often incomplete. Indeed, it frequently happens that all the varieties are not assessed on all the environments.

Format

A data-frame with 16 rows and 10 columns

Examples

if (FALSE) {
data(geno)
ncomp <- estim_ncpPCA(geno)
res.imp <- imputePCA(geno, ncp= ncomp$ncp)
res.pca <- PCA(res.imp$completeObs)
}
