pair_cosine: Calculation of cosine similarity

In macintyrelab/CNpare: Comparing tumour copy number profiles

Calculation of cosine similarity

Description

This function calculates the Cosine similarity

Usage

pair_cosine(cell, ccle, ccle.name, pvalue)

Arguments

cell	vector with bin-level copy number values of one sample
ccle	vector with bin-level copy number values of the cell model
ccle.name	name of the cell model
pvalue	a logical value to indicate if the empirical pvalue is calculated or not

Value

Cosine similarity

Examples

posBins<-lapply(1,function(chr)
    getBinsStartsEnds(window=1000000, chr, lengthChr[chr]))
ccle_cn<-getCNbins(posBins=posBins, data=cells_segcn, samples=unique(cells_segcn$sample)[1:2])
exp_cell<-as.matrix(ccle_cn[,1])
mod_cell<-as.matrix(ccle_cn[,2])
c<-pair_cosine(exp_cell,mod_cell,unique(cells_segcn$sample)[2],pvalue=FALSE)
