@KTInvasion slide = slice.
@KTInvasion So 2 to a bazillion measurements can be referenced by 1 variable. You can slide, dice, transform, facet, whatever by that 1 var.
@KTInvasion You can collapse a dataset with bazillion individuals x bazillion measurements on each into a bazillion x 3 dataset.
@KTInvasion because it is easier to slice and apply functions to long shaped data that wide shaped data. 1 col vs n cols.
@KTInvasion A is easier for data entry. B is easier for transforming data, applying functions and making faceted plots. R makes A->B easy.
