I think I am whistling in the wind, but is there a modern symbolic debugger for R programmes? I am working through some one else's code, thousands of lines, that has the occasional bug in it, and a lot in my understanding of it. I cannot make setBreakpoint or findLineNum work. I get "No source refs found.". I am starting to loose my mind! A debugger where I could set breakpoints with a little more granularity than the function level and a little more accessible than the trace function. What I ideally want is GDB for R.
trace("f", quote(browser()), 3)
will set a breakpoint at line 3 of function f and
body(f)
will list the body of f showing where the browser command was added.
Of course you could also edit the source of f and just insert a
browser() command yourself.
