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)
```

- angle1
`AgentMatrix`

object representing the moving`agents`

, orNumeric. Vector of angles.

- angle2
`AgentMatrix`

object representing the moving`agents`

, orNumeric. 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`

.

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

could be rotated to produce `angle2`

(i.e., the target heading).

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.
