Permissions problem with rmarkdown and shiny

[Ewen Harrison]

Appreciate any thoughts on this.

Running rstudio server and shiny server (both pro) on ubuntu 13.04.

Rmarkdown created and saved as per a user shiny application in ShinyApps folder.

User 1 accesses their rmarkdown file via server/user1/app/index.Rmd with no problem.

User 2 attempts to access rmarkdown via server/user2/app/index.Rmd and gets "Error: cannot open connection".

This is because the folder tmp/rmarkdown is created with user1s permissions and no subsequent user can write to this.

Deleteing /tmp/rmarkdown allows user2 to access server/user2/app/index.Rmd as expected.

My fault or bug?

Thank you!

Ewen

Ewen,

I see a lightly different behavior. What version of Shiny Server are you using? (shiny-server --version)

Also, is your code saving any files on the disk? 

Do you see this behavior with all Rmd files?

sudo chmod 777 -R /tmp did the trick for me
