Examples

 
## Load data  
methylfile <- system.file('extdata', 'methylData.rds', package='BioMM')  
methylData <- readRDS(methylfile) 
dataY <- methylData[,1]
methylSub <- data.frame(label=dataY, methylData[,c(2:1001)])  
library(ranger)  
library(BiocParallel)
param1 <- MulticoreParam(workers = 1) 
param2 <- MulticoreParam(workers = 10) 
predY <- predByCV(methylSub, repeats=1, nfolds=10,   
                  FSmethod=NULL, cutP=0.1, 
                  fdr=NULL, FScore=param1, 
                  classifier='randForest',
                  predMode='classification', 
                  paramlist=list(ntree=300, nthreads=1),
                  innerCore=param2)  
accuracy <- classifiACC(dataY=dataY, predY=predY)
print(accuracy)
