go_gene2go | parse gene2go file
go_obo | simple vectorized parsing of GO OBO file without any dependencies (beyond dplyr/tibble/tidyr)
hgnc_idmap_table | Parse HGNC gene identifier lookup table that was downloaded from genenames.org into a table with HGNC ID, symbol, synonym (NA if unavailable), entrez ID
lighten_color | naively lighten a color by mixing in white
load_genesets_gmtfile | parse genesets in GMT format where gene identifiers are numeric Entrez gene IDs
load_genesets_go_bioconductor | Load GO annotations via Bioconductor packages (e.g. org.Hs.eg.db for Human)
load_genesets_go_fromfile | construct a geneset table from gene2go and OBO files
load_genesets_syngo | parse genesets from the SynGO database
minlog10_fixzero | -log10 transform a vector of p-values, replacing zeros with some limit/threshold
padjust_genesets | Adjust p-values for all genesets, grouped by 'source' then adjust for the number of 'sources'
partition_genes | Classify genes into 2 groups, e.g. to define significant or topN genes, resulting in a 'signif' column with boolean values
