sd.transectHolder function

Function to compute the sd dispersal distance along a transect of seed traps.

This function computes the standard deviation of the dispersal distances along a transect of seed traps.

sd.transectHolder(transectHolder)

Arguments

• transectHolder: an object representing a transect of seed traps.

Returns

The standard deviation of the seed dispersal distances is returned.
