Version 1.19, 11/29/2010:

Major changes:

Added a tutorial on genetic map construction; find it within the
package at docs/geneticmaps.pdf, or (more simply, probably), find it
on the web at http://www.rqtl.org/tutorials/geneticmaps.pdf

Added two additional formats to summary.scanone(), "tabByCol" and
"tabByChr". These produce tables of LOD peaks organized by LOD
score column or by chromosome. The tables include approximate
confidence intervals for QTL location (as calculated by the lodint()
or bayesint() function; which one is indicated by the new argument
ci.function). Here's an example:

bp:
chr pos ci.low ci.high lod pval
c1.loc44.5 1 47.8 35.5 85.0 3.56 0.007
D4Mit164 4 29.5 18.8 30.6 8.09 0.000

sqrt:
chr pos ci.low ci.high lod pval
c1.loc44.5 1 47.8 35.5 84.8 3.63 0.007
D4Mit164 4 29.5 17.2 30.6 8.08 0.000
