Arguments

x

ScoreMatrix or a ScoreMatrixList object

bin.num

integer number of bins in the final matrix

fun

character vector or an anonymous function that will be used for binning

Examples

# binning the columns in a ScoreMatrix object
library(GenomicRanges)
target = GRanges(rep(c(1,2),each=7), IRanges(rep(c(1,1,2,3,7,8,9), times=2), width=5),
weight = rep(c(1,2),each=7),
strand=c('-', '-', '-', '-', '+', '-', '+', '-', '-', '-', '-', '-', '-', '+'))
windows = GRanges(rep(c(1,2),each=2), IRanges(rep(c(1,2), times=2), width=5),
strand=c('-','+','-','+'))
sm = ScoreMatrix(target, windows)
bin = binMatrix(sm, bin.num=2)
