Error in enrichKEGG for a model organism
Entering edit mode
Last seen 7 weeks ago

Hello everyone! To gain familiarity with enrichment analysis, I'm using a model organism to understand how the packages work. Then, I'll be able to conduct analyses on my non-model organism, which presents various challenges, and for which I've opened another question.

Here the code, thank you!

James showed you in his post below what format decs should be in order to have it compatible with enrichKEGG, so that question is 'formally' answered.

Based on your previous posts on the support forum it is clear you are struggling with performing GO or KEGG-based enrichment analysis on your list of identifiers. Yet, the only thing I/we know is that these ids are somehow related to the bug Acinetobacter baumannii, but what ids exactly your are working with is still unclear to me. So, I strongly encourage you to be more clear on what exactly you try to achieve! You would do this by describing what type of experiment you actually did (sequencing, proteomics, ...), how your processed the output, including which method and reference genome or proteome you used for that, and by showing a summary/list of (say) 15 real identifiers your are working with.

Your 'decs' object is a long string, rather than a long vector. You could instead do

dec <- scan("de.txt","c")

Which will result in something like

which is what you want. And then

> z <- enrichKEGG(dec, "pae")

It works as expected.
