compute.Individual.PDI(id, df, polygon, polyscale)

`x`	- Individual object
`x`	- Spatial Polygon
`df1`	- data frame of coordinates of this animal id
`df2`	- data frame of coordinates of other animals from the same population
`id`	- animal id
`df`	- data frame of the Individuals of the same population
