shinyapps: cannot load ecoli data sets

[ebey]

The shinyapps webpage grays out when trying to load networks ecoli1 or ecoli2, but the networks can be loaded when running the app through RStudio.

Initial investigation shows that this is not caused by errors in trying to calculate centralization measures at startup. Currently looking into worker settings through shinyapps.io

Using https://ebey.shinyapps.io/statnetWeb to diagnose:

shinyapps log doesn't have any errors, or any messages at all after startup:

I run the app in local, for two ecoli networks, getting error Error in solve.default(A, tol = tol) : system is computationally singular: reciprocal condition number = 1.7338e-21

other networks are fine.

Thanks @kecoli

Those errors are from computing the information centrality and eigenvector centrality measures, but it seems to be a separate issue because when I comment them out and re-deploy (which I have done in https://ebey.shinyapps.io/statnetWeb) the app still dies when I select either of those networks.

Issue is fixed after increasing application size on shinyapps.io to XXL
