View source: R/getLncGenePairs.r

Description

Get the co-express lncRNA-mRNA interactions reached a significant positive threshold. These lncRNAs-mRNAs pairs are competitivly rugulated.

Usage

1
getLncGenePairs(GeneExp,LncExp,a=0.025)

Arguments

GeneExp

A gene expression profile. The first row of gene expression profile is names of mRNA, and the gene expression profile and the lncRNA expression profile must be mached.

LncExp

A lncRNA expression profile. The first row of lncRNA expression profile is names of lncRNA, and the gene expression profile and the lncRNA expression profile must be mached.

a

A parameter,namely the significant positive threshold.

Details

Co-express coefficient for any pair of relations in the candidate LncRNA-mRNA network is calculated basing on matched LncRNA and mRNA expression profiles, those relations had reached a significant positive threshold were retained.

Value

A data frame. The data frame has two columns, the fist is lncRNA names, the other is mRNA names.
