Suppress warning message in R console of shiny

Question

We developed a shiny application. It was showing some warning messages, we never bothered it, because the application is working fine. But, we can\'t distribute the applicat

Answer 1

Wrapping suppressWarnings around your code should work. See ?suppressWarnings. You need to do something like:

atest <- function(n) {warning("a warning"); return(n+1)}
atest(1)
#[1] 2
#Warning message:
#In atest(2) : a warning

suppressWarnings(atest(1))
#[1] 2

But I guess that the better solution is to actually deal with the warning and not just ignore it.
