OM_class: OM class
In eeholmes/WRAP: WRAP Location Study

Description

This is the format for all output for the OM functions. The output is a list with meta A list with elements that describe the model used.

version: Version of WRAP package used.
func: Name of function that produced the grid.
call: Exact call used to run model.
sim.seed: The random seed used for the simulation to replicate the results .Random.seed <- sim.seed before rerunning the OM function.
entries for all the arguments to the function (function dependent)
covariates: The covariates included in the model.
grid.dimensions: c(nrow, ncol, n cells).
grid.resolution: c(x, y)
grid.extent: c(xmin, xmax, ymin, ymax)
grid.crs: grid coordinate system
grid.unit Eg. "degree" Add units for clarity. NA if grid is simulated for example a 20x20 grid.
time: c(start date, end date). For example c(2001, 2101)
time.unit = "year" for yearly.

grid A data frame with a row for each grid square. The data frame has the following columns. Other columns can be added but at minimum the following are provided:

lat
lon
year
pres Presence/absence as 0/1
suitability
columns for the covariates (one column for each)
covariates: The covariates included in the model. The number of covariates will vary by model.
