Description
This is the gorillas dataset from the package spatstat (also featured in inlabru), formatted for use with scampr models. Describes the nesting locations of gorillas, and associated predictors, in Kagwene Gorilla Sanctuary in Cameroon.
Usage
gorillas
Format
A data frame with 26020 rows and 11 variables:
- x
Horizontal coordinate in units Easting.
- y
Vertical coordinate in units Northing.
- quad.size
Size of the quadrat in Northing/Easting units squared.
- aspect
Compass direction of the terrain slope. Categorical, with levels N, NE, E, SE, S, SW, W and NW, which are coded as integers 1 to 8.
- elevation
Digital elevation of terrain, in metres.
- heat
Heat Load Index at each point on the surface (Beer's aspect), discretised. Categorical with values Warmest (Beer's aspect between 0 and 0.999), Moderate (Beer's aspect between 1 and 1.999), Coolest (Beer's aspect equals 2). These are coded as integers 1, 2 and 3, in that order.
- slopeangle
Terrain slope, in degrees.
- slopetype
Type of slope. Categorical, with values Valley, Toe (toe slope), Flat, Midslope, Upper and Ridge. These are coded as integers 1 to 6.
- vegetation
Vegetation type: a categorical variable with 6 levels coded as integers 1 to 6 (in order of increasing expected habitat suitability).
- waterdist
Euclidean distance from nearest water body, in metres.
- pres
Binary indicating whether the row is a presence record (1) or a quadrat (0).
