R: Concatenate x,y Coordinate Vectors

concatxy {spatstat.geom} | R Documentation

## Concatenate x,y Coordinate Vectors

### Description

Concatenate any number of pairs of `x` and `y` coordinate vectors.

### Usage

      concatxy(...)

### Arguments

`...` | Any number of arguments, each of which is a structure containing elements `x` and `y`.

### Details

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.

### Value

A list with two components `x` and `y`, which are the concatenations of all the corresponding `x` and `y` vectors in the argument list.

      xy <- list(x=runif(10),y=runif(10))
      new <- concatxy(dat, xy)
