DistancePointLine {LearnGeom}

Computes the distance between a point and a line

Description

DistancePointLine computes the distance between a point and a line

Usage

DistancePointLine(P, Line)

Arguments

P

Vector containing the xy-coordinates of a point

Line

Vector object previously created with CreateLinePoints or CreateLineAngle

Value

Returns the distance between a point and a line. This distance corresponds to the distance between the point and its orthogonal projection into the line

Examples

P <- c(2,1)
P1 <- c(0,0)
P2 <- c(1,1)
Line <- CreateLinePoints(P1, P2)
d <- DistancePointLine(P, Line)
