Example traits data

Description

The traits dataset contains measured abundance of 18 glucosinates and 6 flavonols for 162 Arabidopsis thaliana individuals. The traits2 dataset contains abundance of 20 unidentified mass peaks (mass peak numbers) for 162 Arabidopsis thaliana individuals. Example matrice of phenotypes for each trait (rownames) and sample/individual (columnnames), as numeric or NA when missing:
