In momentuHMM: Maximum Likelihood Analysis of Animal Movement Behavior Using Multivariate Hidden Markov Models
distAngle R Documentation
Calculate distance between points y and z and turning angle between points x, y, and z
Description
Calculate distance between points y and z and turning angle between points x, y, and z
Usage
distAngle(x, y, z, type = "UTM", angleCov = TRUE)
Arguments
x
location 1
y
location 2
z
location 3
type
'UTM' if easting/northing provided (the default), 'LL' if longitude/latitude
angleCov
logical indicating to not return NA when x=y or y=z. Default: TRUE (i.e. NA is not returned if x=y or y=z).
Details
Used in prepData and simData to get distance and turning angle covariates
between locations (x1,x2), (y1,y2) and activity center (z1,z2).
If type='LL' then distance is calculated as great circle distance using spDistsN1, and turning angle is calculated based on initial bearings using bearing.
Value
2-vector with first element the distance between y and z and second element the turning angle
between (x,y) and (y,z).
