r - Error Deploying Shiny App: Unhandled Exception: Invalid control character -

i have app works on local computer. however, when trying deploy shiny app shinyapps.io, doesn't work. following error:

i not sure do.

i have tried installing rcpp in question, an error in deploying shiny app shinyapps.io, didn't work.

i have 2 other files besides ui.r , server.r in directory, 1 csv file read , 1 r object file (i used save save , load r using load - save time). have tried , without these files in directory , gives same error either way.

i have mac , r version 3.3.3. rsconnect version 0.7.
