Accessor function for the 'sampleStrata' information in a mRMRe.Data object

Description

The sampleStrata vector consists of a sampling stratification that will be used in computing mutual information between features. If known batch effects or sample stratification is present between samples, identify such subsets using this.

Usage

## S4 method for signature 'mRMRe.Data'
sampleStrata(object)
## S4 replacement method for signature 'mRMRe.Data'
sampleStrata(object) <- value

Arguments

object	a mRMRe.Data object.
value	a factor vector identifying the stratification of samples.

Examples

set.thread.count(2)
data(cgps)
feature_data <- mRMR.data(data = data.frame(cgps.ge))

# No stratification (default)
sampleStrata(feature_data)

# Random stratification 
sampleStrata(feature_data) <- as.factor(sample(c(0,1), 
  sampleCount(feature_data), replace=TRUE))
# Show result
sampleStrata(feature_data)
