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.
