In REPTILE: Regulatory DNA Element Prediction

Description

Internal function to learn a random forest classifier

Usage

reptile_train_one_mode(epimark, label,
                       family, ntree, nodesize)

Arguments

epimark	data.frame instance from read_epigenomic_data, which containing intensity and intensity deviation values of each mark for each DMR or query region.
label	factor instance from read_label, containing the label of each query region. The possible values and their meanings of a label are: 0 (not enhancer), 1 (enhancer) and NA (unknwon and will be ignored).
family	Classifier family used in the enhancer model Default: RandomForest Classifiers available: - RandomForest: random forest - Logistic: logistic regression
