Hello,
I'm attempting to use the GOstats package to do a differential KEGG pathway analysis in wheat (non-model organism without an organism package).
I'm following the guidelines from GOstats for unsupported organisms here. The problem is at step 1.3, using KEGGFrame in a KeggID/GeneID data frame, where the function returns a message saying the KEGG Ids are not valid. The problem also occurs when replacing "taes" with "eco" in KeggLink and using this data in KEGGFrame.
The fact that the KEGG ids were obtained using KEGGREST suggest that they are legitimate Kegg IDs (and searching them on Kegg website returns valid genes). Has anyone seen this before and any ideas how to get over it? I've tried not removing the path id text with stringr, but that didn't help.
I've just freshly installed R4.4 and updated all packages on Rstudio, however I code in Microsoft visual studio code.
Hope someone is able to help. Best regards, GV Yoshikawa
