sphericity | R Documentation |

Given a set of locations, this function approximates the sphericity of the set by calculating the bivariate 95 the set.

sphericity(x, y)

`x` |
A vector of x coordinates. |

`y` |
A vector of y coordinates. |

A single numeric value corresponding to the ratio between the minor and major axis of the bivariate 95 close to 1 indicates that the set is approximately circular; a value close to 0 indicates that the set is strongly elongated.

x <- rnorm(25) y <- rnorm(25, sd = 3) sphericity(x, y)
