Slick Call Stacks
Better looking call stacks after an error.
source("https://install-github.me/mangothecat/tracer")library(tracer)After an error, call tb() instead of
traceback(), to get a nice error stack summary:
To browse the code at the locations of the calls, supply the number
of the call to tb():
Note that tracer can often show the (deparsed) source
code of the call location, even if the original R source code is no more
available, like in the case of installed packages.
tracer sets the error handler via
options(error = ...). If the user changes the error handler
manually, then tracer will not work.
