This function will retrieve the position of a vertex or a face on a hexagrid or trigrid object.
Usage
pos(gridObj, names, output = "polar")
Arguments
- gridObj
a (hexagrid or trigrid) Icosahedral grid object.
- names
(character) Vector of the names that are to be looked up.
- output
(character) The coordinate system in which the names are to be shown: use "polar" for longitude-latitude and "cartesian" for XYZ output.
Details
Vertex and face names can be mixed in a single names argument.
Examples
g <- trigrid(c(4,4))
pos(g, c("F2", "P6", "dummyname"))
#> long lat
#> F2 -54 87.86095
#> P6 126 86.03532
#> dummyname NA NA
