I am trying to use this package graphite for pathway analysis from gene expression data of Rice( Oryza sativa) . However, I cannot retrieve the pathways from kegg using this package. I am using this code
osa <- pathways("Oryza sativa" , "kegg")
Firstly can it be used for organisms other than listed in
pathwayDatabases() ? If so, how to do that ?
Thanks in advance.
