Possible clarification/correction...(apologies in advance if I'm being redundant)
If I put the following four lines in a script whose file name is "junk.r": log(3) log(4) log('a') log(5) then it generates an error message, as expected: > source('junk.r') Error in log("a") (from junk.r#3) : non-numeric argument to mathematical function Note that the error message references the line number (correctly). So there must be something somewhere that keeps track of the script's line numbers. Finding it, however, is more than I'm ready to tackle. -Don -- Don MacQueen Lawrence Livermore National Laboratory 7000 East Ave., L-627 Livermore, CA 94550 925-423-1062 On 4/6/17, 12:30 PM, "R-help on behalf of Bert Gunter" <r-help-boun...@r-project.org on behalf of bgunter.4...@gmail.com> wrote: I believe the answer is: No. "Line number" is an ambiguous concept. Does it mean physical line on a display of a given width? a line of code demarcated by e.g. <CR> ; a step in the execution of script (that might display over several physical lines?) However, various IDE's have and display "line numbers," so you might try researching whichever one that you use.
