Angles for an XY coordinates matrix
aue.dataAngle(XY, maxpi = FALSE, deg = FALSE, latlon = FALSE)
XY matrix with projected coordinates
angles bounded between 0 - pi?
angles in decimal degrees?
Are the coordinates in decimal degrees format? Defalut FALSE. If TRUE,
the coordinates must be in a matrix/data frame with the longitude in the first
column and latitude in the second. The position is projected onto a plane in
meters with the function geoXY
.
