How to extract gene ID corresponding to TAIR (arabidopsis key type)? feat. enrichWP

Question

[hellokwmin]

Hello.

I am trying to perform enrichWP function using R.

I order : enrichWP(geneList, organism = "Arabidopsis thaliana"), but I got this error message as below:

> enrichWP(GO$geneList, organism = "Arabidopsis thaliana") 
--> No gene can be mapped....
--> Expected input gene ID: 842096,830997,841142,824747,842958,826535
--> return NULL...

It seems that I need to covert my TAIR id (e.g. AT2XXXXX) to gene ID as suggested by system shown above...

or, can I put some option to read my TAIR ID when implementing enrichWP function?
