chr_lengths

Calculate chromosome lengths

Calculate chromosome lengths for a map object

chr_lengths(map, collapse_to_AX = FALSE)

`map`	A list of vectors, each specifying locations of the markers.
`collapse_to_AX`	If TRUE, collapse to the total lengths of the autosomes and X chromosome.

We take diff(range(v)) for each vector, v.

A vector of chromosome lengths. If collapse_to_AX=TRUE, the result is a vector of length 2 (autosomal and X chromosome lengths).
