pos

Position of face centers and vertices on a grid

This function will retrieve the position of a vertex or a face on a hexagrid or trigrid object.

pos(gridObj, names, output = "polar")

`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.

Vertex and face names can be mixed in a single names argument.

A numeric matrix.

g <- trigrid(c(4,4))
pos(g, c("F2", "P6", "dummyname"))
