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.
