quipu-package
(Package: quipu) :
Quipu-type charts for a set of SSR markers.
The chart shows SSR marker weights on a linear scale where each allele or 'gel band' is represented by a circle. The circle's diameter is sized inversely by its rareness within the set of accessions in the database at hand and within that locus. The purpose is to facilitate the visual screening and comparison of genotypes with regard to these two questions:

(Package: quipu) :
Creates quipu-type charts for a set of SSR markers
The chart shows SSR marker weights on a linear scale where each allele or 'gel band' is represented by a circle. The circle's diameter can be sized and colored by its rareness. Two parameters 'col.fig' and 'grp.size'allow to do so. The 'rareness' can be calculated - by default - based only on the dataset at hand or by a supplied reference table. To do so, the parameter 'obs.alls.frq' expects a dataframe with three columns named 'Marker', 'Marker.Size' and 'Frequency'. Another parameter, 'obs.alls.frq.ref' should be used to supply a character string containing the reference to the source of allele frequencies being used. For visualization purposes, the class breaks can be defined using a vector of three numeric values in the range between 0 and 1 and be passed to the parameter 'grp.brks'. The default is 0.01, 0.05 and 0.001.
