subHeadings: Subtract headings

Description

Compute the difference between headings.

Usage

subHeadings(angle1, angle2, range360 = FALSE)

# S4 method for numeric,numeric subHeadings(angle1, angle2, range360 = FALSE)

# S4 method for agentMatrix,numeric subHeadings(angle1, angle2, range360 = FALSE)

# S4 method for numeric,agentMatrix subHeadings(angle1, angle2, range360 = FALSE)

# S4 method for agentMatrix,agentMatrix subHeadings(angle1, angle2, range360 = FALSE)

Value

Numeric. Vector of the smallest angles in degrees by which angle1 could be rotated to produce angle2

(i.e., the target heading).

Arguments

angle1

AgentMatrix object representing the moving agents, or

          Numeric. Vector of angles.

angle2

AgentMatrix object representing the moving agents, or

          Numeric. Vector of angles.

range360

Logical. If range360 = TRUE, returned values are between 0 and 360 degrees; if range360 = FALSE, returned values are between -180 and 180 degrees. Default is range360 = FALSE.

Details

This function does the opposite as the one in NetLogo where angle1 is the target heading.

    `angle1` and `angle2` must be of the same length or if different,
    one of them must be of length 1.

Positive values mean clockwise rotations, negative value mean counterclockwise rotations.
