It may help to call the original 'proj
ce).
Thank you very much,

Dear List-Members,
I try to implement a proj.line3d method and to overload this method as follows:
proj.line3d <- function(p, x, y, z, ...)
UseMethod("proj.line3d")
proj.line3d.numeric = function(p, x, y, z, ...) {
# ...
}
proj.line3d.matrix = function(p, x, y, z, ...) {
# ...
}
The code
