Dear All, is there a package in R that implements parametric and non parametric genetic linkage analysis (with both case/control or quantitative phenos)? I tried using Merlin, which could not deal with pedigrees the size I have, and SimWalk2 does not look like the answer either --for instance I do not have a recombination map, just a position map and I doubt SW2 would like that. I had a look in the archives and on CRAN but nothing popped out as being the R equivalent of linkage analysis software (though I just had a quick look). Best, Federico -- Federico C. F.
