make.so.data {stocc} | R Documentation |
Create spatial data object for model fitting via spatialOccupancy
function
Description
This function takes an observation data frame and a data frame of site
characteristics and combines them together for analysis with the
spatial.occupancy
function.
Usage
make.so.data(visit.data, site.data, names)
Arguments
visit.data |
A data frame that contains the observed occupancy for each site and any detection related covariates. |
site.data |
A data frame that contains the site id, coordinates, and any habitat related covariates that might influence the occupancy process |
names |
A named list with the following elements: (1) |
Details
This function combines the two data frames and assigns names so that
spatial.occupancy
knows which columns to use. It also performs
some rudimentary error checking to make sure the data is in the proper form
(e.g., the site IDs in the visit data frame must be contained in the site
IDs for the site data frame)
Value
An so.data
object is a list with elements equal to the two
data frames. Attributes are set giving the names of columns of interest
