`inRadius.Rd`

Report the patches or turtles among `agents2`

within given distances of
each of the `agents`

. Currently, this function multiplies `radius`

by
1.0000001 so that the response of `inRadius`

is inclusive.

inRadius(agents, radius, agents2, world, torus = FALSE) # S4 method for matrix,numeric,matrix inRadius(agents, radius, agents2, world, torus = FALSE)

agents | Matrix (ncol = 2) with the first column "pxcor" and the second column "pycor" representing the patches coordinates, or AgentMatrix object representing the moving agents. |

distances for each `agents`

which are represented by the "id" column, if
`agents2`

are patches, or

Matrix (ncol = 2) with the first column "who"
representing the "who" numbers of the
turtles among `agents2`

within `radius`

distances for each `agents`

which are represented by the "id" column, if
`agents2`

are turtles.

Distances from/to patches are calculated from/to their center.

If `torus = FALSE`

, `world`

does not need to be provided.

If `torus = TRUE`

, the `radius`

distances are calculated
around the sides of the `world`

to select `agents2`

.
