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
