?message talks about conditions and restarts, which leads to

   withCallingHandlers({
       x <- 1 + 2
       message("working...")
       x
   }, message = function(m) {
        cat("got message:", conditionMessage(m), "\n")
        invokeRestart("muffleMessage")
   })

which prints

got message: working...
