Accession means for the flowering time data contained in
Data-frames with flowering time means:
a factor, the levels being the accession or ecotype identifiers
Flowering time under long days, in number of days
Flowering time under long days and vernalization, in number of days
Following Kruijer et al. (appendix A) these means were defined as the least-squares estimate for the factor accession, in a linear model containing both accession and replicate effects. Consequently there are differences compared to Atwell et al. (2010), where just the arithmetic averages are considered.

Together with the covariance matrices contained in
R_matrix_LDV, the means contained in
can be used to estimate heritability, using the function
