can not save my network as XGMML in




I have a very basic question.

I have a network which is an igraph object I want to save it as XGMML file. When I run the following command, locally I get an xgmml file in the directory of my app, (www folder). But when I deploy it to the I no longer get an xgmml file in my directory. How can I fix that issue?

saveNetwork(network = ntwrk, name="network", file = "network", type="XGMML")

Appreciate your support!
Thank you
