The environmeny in which the files in the R/ directory should

The environment in which global.R should be evaluated. If

shiny.autoload.r is set to TRUE.
The files are sourced in alphabetical order (as determined by
list.files). global.R is evaluated before the supporting R files in the
R/ directory.
