| rlang_backtrace_on_error {rlang} | R Documentation |
Errors thrown with abort() automatically save a backtrace that
can be inspected by calling last_error(). Optionally, you can
also display the backtrace alongside the error message by setting
the option rlang_backtrace_on_error to one of the following
values:
"reminder": Display a reminder that the backtrace can be
inspected by calling last_error().
"branch": Display a simplified backtrace.
"collapse": Display a collapsed backtrace tree.
"full": Display the full backtrace tree.
Call options(error = rlang::entrace) to instrument base
errors with rlang features. This handler does two things:
It saves the base error as an rlang object. This allows you to
call last_error() to print the backtrace or inspect its data.
It prints the backtrace for the current error according to the
rlang_backtrace_on_error option.
# Display a simplified backtrace on error for both base and rlang
# errors:
# options(
# rlang_backtrace_on_error = "branch",
# error = rlang::entrace
# )
# stop("foo")
