Report the amount by which the `turtles`

' coordinates xcor would change
if the `turtles`

were
to move forward the given distances with their current headings.

dx(turtles, dist = 1)
# S4 method for agentMatrix,numeric
dx(turtles, dist = 1)
# S4 method for agentMatrix,missing
dx(turtles)

## Arguments

turtles |
AgentMatrix object representing the moving agents. |

dist |
Numeric. Vector of distances the `turtles` would have to
move forward to
compute the increment values. Must be of length 1 or of length
`turtles` . The default value is `dist = 1` . |

## Value

Numeric. Vector of length `turtles`

.

## Details

Report the sine of the `turtles`

' heading multiplied by the `dist`

values. Heading 0 is north and angles are calculated in degrees in a
clockwise manner.
