[Bioc-devel] check shiny app: issue with global variables: input$Vars is not found

Hi Karim,

I assume this is because the input parameter only assess the ones that are
passed on from the ui-environment.
The global variables are available without the 'input' prefix anyways.

For example, if you declared *globalVar2* as a global variable (let's say
in a global.r) then you don't need the input$ prefix.
Variables declared within the ui-function body need to be addressed by
input$.

I hope that helps.

Cheers,

Stefan

Dear R,
usually, Shiny app uses global variables saved in a session.
These variables can be returned by client web page (checkbox or select).

for example:
 FUN1 <- function(input$var1){
 a <-  input$car1 + input$globalVar2
return (a)
}
when I run check package I got error like
object input$globalVar2 not found.

Also the error is possible in running examples. The global variable or
input$var are not found in shiny app.

How we can avoid these issues.
Thanks,
Karim
