How to show error line number in R studio -
is possible see syntax error or runtime error line number (highlight also) generated after running code in r studio?
i searched options couldn't find.
first, have @ ?traceback
.
there many ways debug r code/script. 1 example.
in rstudio, debug
drop down menu option on error
, choose error inspector
(what think is) easiest debug mode finding line number of error/bug. can choose break in code
show highlighted line of r script contains error.
when error occurs, can click either of small areas marked show traceback
, rerun debug
. screen shot below shows effect of clicking "show traceback" (hence says "hide traceback"). tells me error occurred when r attempted call sample
(the third call). length
had not yet been defined.
