All chromosomes in <code>object</code> should have corresponding chromosomes in <code>map</code>, and markers must be in the same order in the two maps. There must be at least two markers on each chromosome in <code>map</code> that appear in <code>object</code>.</p> </td></tr> </table> <h3>Details</h3> <p>The positions of pseudomarkers are determined by linear interpolation between markers. In the case of pseudomarkers beyond the ends of the terminal markers on chromosomes, we use the overall lengths of the chromosome in <code>object</code> and <code>map</code> to determine the new spacing. </p> <h3>Value</h3> <p>The input <code>object</code> with the positions of LOD scores revised to match those in the input <code>map</code>.</p> <h3>Author(s)</h3> <p>Karl W Broman, <a href="mailto:broman@wisc.edu">broman@wisc.edu</a> </p> <h3>See Also</h3> <p><code><a href="replace.map.html">replacemap.cross</a></code>, <code><a href="est.map.html">est.map</a></code>, <code><a href="replacemap.scanone.html">replacemap.scanone</a></code> </p> <h3>Examples</h3> <pre> data(hyper) origmap <- pull.map(hyper) newmap <- est.map(hyper) hyper <- replacemap(hyper, newmap) hyper <- calc.genoprob(hyper, step=0) out <- scantwo(hyper, method="hk") out.rev <- replacemap(out, origmap) </pre> <hr /><div style="text-align: center;">[Package <em>qtl</em> version 1.46-2 <a href="00Index.html">Index</a>]</div> </body></html>
