isXmarker

<p>A marker object. (If <code>x</code> is not a marker object, the function
returns FALSE.)</p>

<p>Tests if the <code>chrom</code> attribute of a marker is either "X" or "23".</p>

A lightweight, but comprehensive collection of tools for creating,
manipulating and visualising pedigrees and genetic marker data. Pedigrees
can be read from text files or created on the fly with built-in functions.
A range of utilities enable modifications like adding or removing individuals,
breaking loops, and merging pedigrees. Pedigree plots are produced by wrapping
the plotting functionality of the 'kinship2' package.
