Compute the difference between `headings`

.

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)

## 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` . |

## Value

Numeric. Vector of the smallest angles in degrees
by which `angle1`

could be rotated to produce `angle2`

(i.e., the target heading).

## 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.
