)Arguments
- go_anno
Dataframe: GO and KEGG annotation of background genes (1st-col: Genes, 2nd-col: biological_process, 3rd-col: cellular_component, 4th-col: molecular_function, 5th-col: kegg_pathway).
- degs_list
Dataframe: degs list.
- padjust_method
Character: P-value adjust to Q-value. Default: "fdr" (false discovery rate), options: "holm", "hochberg", "hommel", "bonferroni", "BH", "BY", "fdr", "none".
- pvalue_cutoff
Numeric: P-value cutoff. Recommend: small than 0.05.
- qvalue_cutoff
Numeric: Q-value cutoff. Recommend: small than 0.05.
- category_num
Numeric: categories number to display. Default: 20, min: 1, max: NULL.
- net_layout
Character: network layout. Default: "circle", options: 'star', 'circle', 'gem', 'dh', 'graphopt', 'grid', 'mds', 'randomly', 'fr', 'kk', 'drl' or 'lgl'.
- net_circular
Logical: network circular. Default: TRUE, options: TRUE, FALSE.
- low_color
Character: low value (p-value or q-value) color (color name or hex value).
- high_color
Character: high value (p-value or q-value) color (color name or hex value).
