Hello,

I'm trying to export a KEGG using the Pathview package. I'm interested on KEGG non-native plot (kegg.native = F). It works like a charm however it only exports the plot to PDF format. Is there any workaround to generate the plot also in PNG format?

pathview(gene.data  = geneList,
                     pathway.id = "hsa04110",
                     species    = "hsa",
                     limit      = list(10, cpd=1),
                     kegg.native = F)

I've been trying with keggview.graph() but I got stuck.

Regards,
Guillermo.

If you use the patch that I just created (https://github.com/dondelelcaro/pathview) you can call png() before calling pathview(...,write.plot=FALSE) if that's helpful.

Guillermo, Currently, Pathview only outputs graphviz view (non-native KEGG graphs) in pdf format. If you png file is desirable you may open that in Illustrator and save it in png or other formats. We will add the png format option if we see more need from the users. Weijun
