Description

splitData splits processed ChIP data into training and testing sets.

Usage

splitData(ChIPscore,dist = c(80,20), as.proportion = TRUE)

Arguments

ChIPscore	ChIPscore object as returned by processingChIP
dist	If as.proportion is to TRUE, split the data into desired proportions. Default sets 80% training and 20% testing. If as.proportion is to FALSE,a vector of 4 numeric values describing start and end of training and testing respectively.
as.proportion	Logical describing if values provided to dist should be treated as % of training and testing or if dist should be considered as start and end of loci selected for training and testing respectively.
