R: how to debug the errors

Just some tips:

options(error=recover):  it will tell R to launch debug section and you can choose which one to debug


options(show.error.locations=TRUE):   let R show the source line number

Something else:

use traceback() to locate where the last error message is and then use browser() to run the function again to check what is wrong.
