obsIndexSpatial R Documentation
Relative observation index (Spatial)
Description
This function extracts the proportion of visits (or observations) detecting a
focal species to all visits (or observations) over space.
Usage
obsIndexSpatial(x, focalSp = NULL, visits = TRUE, fs.rm = TRUE, norm = TRUE)
Arguments
x
an object of class ‘SummarizeBirds’.
focalSp
the focal sp to look for
visits
if TRUE (default) the observation index is calculated over number
of visits, else uses the number of observations.
fs.rm
if TRUE, assumes that the observations for the focal species are
included in 'group' and will remove them
norm
if TRUE, the result is normalized to a 0-1 range
Value
A spatial object
