## Calculate x and y Coordinates for A Quadratic Bezier Curve

### Description

Calculate x and y coordinates for a quadratic Bezier curve between two points with the equation: B(t) = (1-t) ((1-t)P0 + tP1) + t((1-t)P1 + tP2) where P0 is the start point, P2 is the end point, and P1 is the control point. P1 will be adjusted based on the distance of two points.

### Usage

        getBezierCurve(lineStart, lineEnd, totalPoints)

### Arguments

`lineStart` | numeric vector, the coordinate of a point where Bezier line starts
`lineEnd` | numeric vector, the coordinate of a point where Bezier line ends
`totalPoints` | non-negative numeric, total number of points that form a Bezier line

### Value

`posX` | x coordinates of points that form Bezier line
`posY` | y coordinates of points that form Bezier line

### Examples

        lineStart   <- c(0, 1)
        lineEnd     <- c(1, 0)
        totalPoints <- 2000
        the_line <- getBezierCurve(lineStart, lineEnd, totalPoints)
