Concatenate x,y Coordinate Vectors
Concatenate any number of pairs of x and y
coordinate vectors.
concatxy(...)
... |
Any number of arguments, each of which is a structure
containing elements |
This function can be used to superimpose two or more point patterns
of unmarked points (but see also superimpose which is
recommended).
It assumes that each of the arguments in
... is a structure containing (at least) the elements
x and y. It concatenates all the x elements
into a vector x, and similarly for y, and returns these
concatenated vectors.
A list with two components x and y, which are the
concatenations of all the corresponding x and y
vectors in the argument list.
