Usage

## S3 method for class 'mRMRe.Data':
subsetData(object, row_indices, column_indices)

Arguments

object

a mRMRe.Data object.

row_indices

An integer vector of the rows to be included in the subset.

column_indices

An integer vector of the columns to be included in the subset.

Examples

data(cgps)
feature_data <- mRMR.data(data = data.frame(cgps.ge))
# Subset the same dimensions, equivalent to making a copy
feature_data_copy <- subsetData(feature_data, 
    row_indices=sampleCount(feature_data),
		column_indices=featureCount(feature_data))

# Use only half of the samples
feature_data_samples <- subsetData(feature_data, row_indices=sampleCount(feature_data)/2)

# Use only half of the features
feature_data_features <- subsetData(feature_data,
    column_indices=featureCount(feature_data))
