goodnessOfFit: Goodness of fit results of the iC10 classifier

In iC10: A Copy Number and Expression-Based Classifier for Breast Tumours

Goodness of fit results of the iC10 classifier

Description

Goodness of fit results of the iC10 classifier: this function computes correlations between the signatures of the training dataset and the classified features.

Usage

goodnessOfFit(obj, iC10=1:10, newdata=NULL,...)
## S3 method for class 'iC10'
goodnessOfFit(obj, iC10=1:10, newdata=NULL,...)

Arguments

obj	An object of iC10 class.
iC10	Groups to compute goodness of fit.
newdata	The feature data to compute the goodness of fit. Must be the samples classified in obj. It can be a call to matchFeatures or normalizeFeatures. If NULL, obj$fitted is used.
...	Additional arguments passed to cor (like method; Default is pearson)

Value

It prints the correlation for each iC10.
