Flatten nested enrichment results

Source: R/flatten_enrich.R
flatten_enrich.Rd

Flattens the nested enrichment result structure returned by enrichGO_list(), enrichR_list(), or enrich_msigdb() into a flat named list of data frames or enrichResult objects. This is useful for exporting results to other tools such as DeeDeeExperiment.

Usage

flatten_enrich(enrich_list)

Arguments

enrich_list

Output of enrichGO_list(), enrichR_list(), or enrich_msigdb(); or a named list combining several such outputs (e.g. list(GO = go_res, MSigDB = msigdb_res)).

Value

A flat named list of data frames or enrichResult objects with DeeDeeExperiment-compatible names and columns (e.g. "clusterProfiler_BP_1", "enrichr_DSigDB"). Returns an empty list if enrich_list is empty.

Examples

data(example_go)
enrich_flat <- flatten_enrich(example_go)
str(enrich_flat, max.level = 1)
#> List of 4
#>  $ clusterProfiler_BP_1:Formal class 'enrichResult' [package "enrichit"] with 15 slots
#>  $ clusterProfiler_BP_2:Formal class 'enrichResult' [package "enrichit"] with 15 slots
#>  $ clusterProfiler_CC_1:Formal class 'enrichResult' [package "enrichit"] with 15 slots
#>  $ clusterProfiler_CC_2:Formal class 'enrichResult' [package "enrichit"] with 15 slots
