vertexradius R Documentation
Calculate the vertex radii of icosahedral grid faces
Description
Great circle distances between face centers and vertices
Usage
vertexradius(x, degree = TRUE)
Arguments
x
(trigrid or hexagrid) Object.
degree
(logical) Should the output be returned in degrees or in kóilometers?
Value
A numeric matrix that matches in structure with the @faces slot of the provided grid x.
Distances measured on each face are in the same row.
Examples
# example grid
g <- trigrid(3)
# all vertexradius
vertrads <- vertexradius(g)
# face average
averages <- apply(vertrads, 1, mean, na.rm=TRUE)
