atl_patch_summary: Get residence patch data.

In pratikunterwegs/atlastools: Tools for Pre-Processing High-Throughput Animal Tracking Data

Description

The function atl_patch_summary can be used to extract patch-specific summary data such as the median coordinates, the patch duration, the distance travelled within the patch, the displacement within the patch, and the patch area.

Usage

atl_patch_summary(patch_data, which_data = "summary", buffer_radius = 10)

Arguments

patch_data	A data.frame with a nested list column of the raw data underlying each patch. Since data.frames don't support nested columns, will actually be a data.table or similar extension.
which_data	Which data to return. May be the raw data underlying the patch (which_data = "points"), or a spatial features (sf-MULTIPOLYGON) object with patch covariates (which_data = "spatial"), or a data.table of the patch covariates without the geometry column (which_data = "summary").
buffer_radius	Spatial buffer radius (in metres) around points when requesting sf based polygons.

Value

An object of type sf or data.table depending on which data is requested.
