A quick reminder to self about error handling in R (baby steps #1)

I guess the below code tells pretty much it all:

tryCatch({
  x = function() {
    stop("hahaha now you blew the code!")
  }
  y = function() {
    x()
  }
  y()
}, error=function(e){
  print(e$call)
  print(e$message)
})

And then sourcing it gives:

x()
[1] "hahaha now you blew the code!"

I guess that's all that there is in practice...
... except maybe that there's a finally parameter included which I never notice :

function (expr, ..., finally) 

So... worth a second look :)

(To be continued...)
