Describes the probability of initiation of agents or events.
*THIS IS NOT FULLY IMPLEMENTED.*

A `SELES`

-like function to maintain conceptual backwards compatibility
with that simulation tool. This is intended to ease transitions from
SELES.

You must know how to use SELES for these to be useful.

`probInit(map, p = NULL, absolute = NULL)`

- map
A

`spatialObjects`

object. Currently, only provides CRS and, if p is not a raster, then all the raster dimensions.- p
probability, provided as a numeric or raster

- absolute
logical. Is

`p`

absolute probabilities or relative?

A `RasterLayer`

with probabilities of initialization.
There are several combinations of inputs possible and they each result
in different behaviours.

If `p`

is numeric or `Raster`

and between 0 and 1, it is treated as an
absolute probability, and a map will be produced with the p value(s) everywhere.

If `p`

is numeric or `Raster`

and not between 0 and 1, it is treated as a
relative probability, and a map will be produced with `p/max(p)`

value(s) everywhere.

If `absolute`

is provided, it will override the previous statements, unless
`absolute = TRUE`

and p is not between 0 and 1 (i.e., is not a probability).
