Hi,

Using clusterprofiler an generated an emap plot from my enrichment data - would anyone be able to tell me where the grouping terms (bottom right) come from / how they are made? They look potentially like they are just picking common words?

Thanks, Matt

Yes, these (the groups) are indeed 'high frequency words' present in the terms/descriptions of the gene set; identified analogous when creating a word cloud.

This is indeed not clearly stated at the help page for the function emapplot, but it becomes obvious if you check the source code at line 523:

https://github.com/YuLab-SMU/enrichplot/blob/ce94b308d0ce5e835117bacd8858aadf2b2de9bc/R/emapplot_utilities.R#L523C44-L524

... you will notice that there the internal function get_wordcloud is called, which can be found here: https://github.com/YuLab-SMU/enrichplot/blob/ce94b308d0ce5e835117bacd8858aadf2b2de9bc/R/wordcloud.R#L26
