unable to deploy application in shiny apps IO

Thanks josh for the quick reply :smiley: ! ,

not solved but closer i guess :stuck_out_tongue:

when upgrading R some package dependencies where not explicitly installed.

the only explicit install i have is:

devtools::install_github("jas1/RBioFabric")
library(RBioFabric)

and looks like ok as said on: 2.4.0.1 Important note on GitHub packages in:
http://docs.rstudio.com/shinyapps.io/getting-started.html#managing-r-versions

the error i got this time: ( just an extract on the last details)

about 2.4 Using your R packages in the cloud:

  • R packages that do not run on Ubuntu Linux : checked, it works on my notebook w/ linux mint
  • R packages that require access to the display (such as Tcl/Tk): is there any quick & friendly way to check all dependency tree ? of an application ?

On the other hand, any good practices to debug this kind of stuff ?

ex: having a visualization of dependency tree for an application?
ex: from an application dependency tree, way to check wich packages are installed explicitly on the local reposiory ?
ex: when upgrading R , and libraries are download again, which are installed and wich not on your local system

Thanks in advance :smiley: !
