Get distance between patches, last point of N to first point of N+1.

Arguments

data	A dataframe of or extending the class data.frame. This must contain two pairs of coordinates, the start and end X and Y coordinates of a feature.
x1	The first X coordinate or longitude; for inter-patch distances, this is the last coordinate (X_end) of a patch n0.
x2	The second X coordinate; for inter-patch distances, this is the first coordinate (X_start) of a subsequent patch n1.
y1	The first Y coordinate or latitude; for inter-patch distances, this is the last coordinate (Y_end) of a patch n0.
y2	The second Y coordinate; for inter-patch distances, this is the first coordinate (Y_start) of a subsequent patch n1.

Value

A numeric vector of the length of the number of patches, or rows in the input dataframe. If the input dataframe has only a single row, the vector has a length of one, and its only element is 0. In all other cases, the vector has as its elements NA, followed by n-1 distances, where n is the number of rows.
