annotateLoops.dge: Annotate enhancer-promoter loops with differential gene...
In diffloop: Identifying differential DNA loops from chromatin topology data

Description Usage Arguments Details Value Examples

annotateLoops.dge adds columns to the rowData slot of a loops object that shows summary statistics corresponding TSS of a gene name based on the genes.tss rowData column. This function should be used following the keepEPloops function.

annotateLoops.dge(lto, deseq_res, multiple = FALSE)

## S4 method for signature 'ANY'
annotateLoops.dge(lto, deseq_res, multiple = FALSE)

`lto`	A loops object whose loops will be annotated
`deseq_res`	A data.frame
`multiple`	Annotate loops with multiple TSS? Default = FALSE

This function links enhancer-promoter loops and differential gene expression results. The rownames of the deseq_res slots should correspond to the gene names in the gene.tss column of the rowData slot of the loops object. The function returns a loops object if multiple is specified as FALSE which is the case by default. Otherwise, if multiple is TRUE, then this function returns a data frame since each loop may have more than moe TSS. One can reproduce this dataframe quickly when multiple = FALSE using the summary() function on the returned loops object.

A loops object if multiple = FALSE or data frame if multiple = TRUE
