Print Call Stack of Last Error
Description
traceback()
prints the call stack of the last error, i.e., the
sequence of calls that lead to the error. This is useful when an
error occurs with an unidentifiable error message.
Currently, this stack is given as a list in .Traceback
.
Usage
traceback()
Examples
foo <- function(x) { print(1); bar(2) }
bar <- function(x) { x + a.variable.which.does.not.exist }
## Not run:
foo(2) # gives a strange error
traceback()
## End(Not run)
## [1] "bar(2)" "foo(2)"
bar
## Ah, this is the culprit ...
