Get geodesic distance between points on the unit sphere

1 |

`p1` |
A |

`p2` |
Same as p1. |

`include.names` |
Boolean. If TRUE then the row and
column names of the returned matrix will be taken from
the points in |

Let *n* denote the number of rows of `p1`

and let *m* denote the number of rows of `p2`

.
Then the returned object is an *n* by *m* matrix
whose entry in position *ij* is the geodesic distance
from the *i*th row of `p1`

to the
*j*th row of `p2`

.

1 2 3 4 5 6 | ```
p1 <- data.frame(diag(3))
colnames(p1) <- c("x", "y", "z")
p1
p2 <- data.frame(x=c(1,0), y=c(0,3/5), z=c(0,4/5))
p2
geoDist(p1, p2, include.names = FALSE)
