Problems running demo

[cjfields]

The RStudio example seems to crash when I try testing it. When downloading and trying this locally I ran into several issues with dependencies such as rlang, which required manual updating:

> runApp('sig-bio-shiny-app.R')
Running Sig-Bio-Shiny v0.2.3 | Sun May 17 14:47:47 2020
Checking if SigBio v0.2.3 Package is installed...
Error: package or namespace load failed for ‘SigBio’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
 namespace ‘rlang’ 0.4.5 is already loaded, but >= 0.4.6 is required
> install.packages("rlang")

Once this was resolved, I used 'Run app' to run the application per the instructions, but ran into the below. Intermittent issues with KEGG availability?

Hi @cjfields! Thank you for using the demo. The Rstudio cloud version have limited RAM memory issue. I'll lunch a demo instance of shinyapps.io soon.

Dependency issue comes mostly while an older version already in use with the namespace. I'm aware of this issue and trying to fix this.

Coming to KEGG pathview there are warnings, as initially no pathway ID is loaded by default. This also will be noted for fix.

Thanks again for bringing these issues into notice.
