Please forgive the cross posting. I sent this to Medstats and have not received any response. I am looking for a good written explanation of components of variance (a.k.a variance components), in particular as they are used in genetic analyses. Does anyone have a suggestion? I am interested in books, articles and on-line material. I intent to give the material to some of my students none of whom

Hi, I'm trying to make a chromosomal map in R by using the locus. I have a list of genes and their locus, and I want to visualise that so you can see if there are multiple genes on a specific place on a chromosome.

Specifics: Response is a numeric positive measurement (of volume, actually); but when it falls below some unknown and slightly random value (depending on how the sample is prepared and measured), it cannot be measured and is recorded as 0.
