Function to get the heights on a landscape for a set
of species points.
For a given set of species coordinates in morphospace,
this function finds the closest point on the landscape
grid, and assigns the values associated to that grid
point to that species.
Arguments
- x
A 'by_Wprime' or 'PO_List' object - contains
the functional adaptive landscapes or Pareto landscapes
you want to extract heights from.
- y
A dataframe containing species information morphospace. The coordinates
columns must be labelled 'x' and 'y'.
Value
A dataframe containing the species information from y,
with additional columns extracted from the landscape data
