debugging - Error handling in R in RStudio -- don't invoke debugger? -


i'm trying create error messages similar can find in r package dplyr don't invoke rstudio's debugger , stop , print informative message.

so example in rstudio if use:

library(dplyr) group_by(blah)

you informative error debugger not invoked "interruption" user minimal, realize issue , fix code. when use 

myfunc<-function(val){   if(val>3) stop("this error", call.=false) }  myfunc(4)

the debugger triggered , it's more unpleasant. how give nice error message out starting debugger? difference in how dplyr creating error messages , mine? did @ github repo wasn't sure.
