Glossary

This is a glossary of key arguments in patter.

.map

.map is terra::SpatRaster (supported on Windows or MacOS) or a character that defines the path to raster (supported on Windows, MacOS and Linux) to a that defines the area of interest. NAs define inhospitable regions (such as land). A planar (e.g., Universal Transverse Mercator) projection with coordinates in metres is currently required.

.model_obs

.model_obs is a named list of ModelObs sub-types (named) and associated parameters (data.table::data.table elements).

.model_move

.model_move is a character string that defines a ModelMove instance.

.state

.state is a character that defines a State sub-type.

.yobs

.yobs is a named list of observational datasets, one for each data type. Element names must correspond ModelObs sub-types defined in Julia. Each element must be a data.table::data.table with the following columns:

• timestamp—a POSIXct vector of time stamps;

• sensor_id—an integer vector of sensor IDs, such as receivers;

• obs—a vector of observations;

• Additional columns that define the parameters of the observation model, as defined by a ModelObs structure;

No other columns should be included.

For real-world analyses, see assemble_*() functions to format datasets as required. Other types of datasets require manual preparation.
