Loads all of the supporting R files of a Shiny application. Specifically,
this function loads any top-level supporting .R files in the R/ directory
adjacent to the app.R/server.R/ui.R files.
loadSupport(
appDir = NULL,
renv = new.env(parent = globalenv()),
globalrenv = globalenv()
)The application directory. If appDir is NULL or
not supplied, the nearest enclosing directory that is a Shiny app, starting
with the current directory, is used.
The environmeny in which the files in the R/ directory should
be evaluated.
The environment in which global.R should be evaluated. If
NULL, global.R will not be evaluated at all.
Since Shiny 1.5.0, this function is called by default when running an
application. If it causes problems, there are two ways to opt out. You can
either place a file named _disable_autoload.R in your R/ directory, or
set options(shiny.autoload.r=FALSE). If you set this option, it will
affect any application that runs later in the same R session, potentially
breaking it, so after running your application, you should unset option with
options(shiny.autoload.r=NULL)
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.
