I released a new version of R/qtl (1.40-8) to CRAN a couple of weeks
ago, but I forgot to announce it or revise its web site
change is the following:
cim() now halts with an error for cross type "4way". The method has
not been implemented for 4-way crosses, and the results are not
meaningful.
As always, I'd appreciate hearing any suggestions or comments or
complaints.
