Enrich analysis using ReactomePA

Question

[shawin]

There is an issue with ReactomPA package. I load the gene list in Reactom online system and I got some result, but when I used the R package , I do not have any result its NULL ? The code is

xx=enrichPathway(gene, organism = "rat")
summary(xx)
Length  Class   Mode
 0   NULL   NULL

[Giovanni M Dall'Olio]

some hypotheses: 1) your genes should be entrez ids encoded as character; 2) the rat organism database is not installed in your system.

@Giovanni I am also using this package but I am getting different error :

Error in x[seq_len(n)] : object of type 'S4' is not subsettable

Any comment on it ?

Thanks
