)Arguments
- kegg_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.
- sign_by
Character: significant by. Default: "p.adjust", options: "pvalue", "p.adjust", "qvalue".
- category_num
Numeric: categories number to display. Default: 30, min: 1, max: NULL.
- font_size
Numeric: category font size. Default: 12.
- 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).
- ggTheme
Character: ggplot2 themes. Default: "theme_light", options: "theme_default", "theme_bw", "theme_gray", "theme_light", "theme_linedraw", "theme_dark", "theme_minimal", "theme_classic", "theme_void".
