GetPerpDist: Get the Perpendicular Distance Between Point and the line...

In joshmarsh/TSPatternQuery: A Time Series Pattern Query Tool Using PIPs and Hybrid Template-Ruleset Matching

Description

This is a helper function for EnumeratePerDist, which in turn is a helper function for GetPIPs. Thus, these functions are highly coupled, and exist simply to make the code more readable. This function is made available to the user because it could be useful on its own.

Usage

GetPerpDist(point, left.point, right.point)

Arguments

point	The point (xts object with length=1) in the middle. Distance will be calculated between this point and the line.
left.point	The left point (xts object with length=1) that will constitute the left endpoind of the line
right.point	The right point (xts object with length=1) that will constitute the right endpoint of the line

Value

The numeric perpendicular distance
