generateExprVal.method.playerout {affy}R Documentation

Generate an expression value from the probes informations


Generate an expression from the probes


  generateExprVal.method.playerout(probes, weights=FALSE, optim.method="L-BFGS-B")


probes a list of probes slots from PPSet.container
weights Should the resulting weights be returned ?
optim.method see parameter 'optim' for the function optim


A non-parametrical method to weight each perfect match probe in the set and to compute a weighted mean of the perfect match values. One will notice this method only makes use of the perfect matches. (see function playerout.costfunction for the cost function).


A vector of expression values.
