A list with small datasets of four different ploidy levels for testing and examples
data(fitPoly_data)list fitPoly_data contains the following items:
ploidy2: a diploid dataset with only the SNP array signal ratios
ploidy3: a triploid dataset with in addition to the signal ratios two data.frames specifying the population structure
ploidy4: a tetraploid dataset similar to the triploid dataset and additionally prior dosage information of the F1 population parents and of a few other samples
ploidy6: a hexaploid dataset similar to the tetraploid dataset and additionally the 7 starting means for some of the markers
Each of the items contains one or more elements, postfixed by 2x, 3x, 4x or 6x depending on the ploidy:
dat: a data.frame with at least columns MarkerName, SampleName and ratio with the signal ratios to be analyzed
pop: a data.frame with columns SampleName and Population, specifying the population to which each sample belongs
pop.par: a matrix specifying what are the parents of each population (if any)
parPriors: a data.frame specifying prior known allele dosages for the F1 parents
sampPriors: a data.frame specifying the prior known dosages for other samples
startmeans: a data.frame with prior known means for the (ploidy+1) mixture model components
In addition the ploidy6 component has elements pop and pop.parents (no suffix) which are equivalent to pop6x and pop.par6x, in the format required by function codomMarker.
