How to use try to print a better call stack?

[Jeremiah Rounds]

Anyone know a trick to print a better call stack for Rhipe?   Some sort of finesse in the Map via tryCatch to dump the call stack?

Right now I am looking at this and thinking bah.  I got a try around foo(e$v), but I need just a little hit.  Pretty sure there is something missing from the environment as it runs locally.  (btw it is foo because it is actually a list of functions that are applying statistical algorithms to the map value).

There were R errors, showing 30:

1(11): 
R ERROR BEGIN (map):
=============

Error in foo(e$v) : object
Autokill is true and terminating job_1444548550266_0092
Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl,  :

I don't think it matters much but for context the full map looks like:

map = expression({

  for(i in seq_along(map.values)){

  v = map.values[[i]]

  k = map.keys[[i]]

 v = analytics$append.proportion(v)

 v = analytics$append.check_analytics_possible(v)

 silent=FALSE

 if(!v$analytics_possible)

   next

 e = NULL

 ret = try({gc()},silent=TRUE)

 e = new.env()

 e$v = v

 v = NULL

 for(foo in analytics){

   try({

     e$v = foo(e$v)

   }, silent=silent)

   

 }

 #return(v)

 v = e$v

 collect(k,v)

  }

})

No pressing need for an answer on this.  Followed my hunch that it was something missing in the environment and cleared out R and found a typo in a function that was causing it to get an argument from a global variable.

Still kind of interested in the answer though for future use.

No edit on these google groups =) 

I remember what I used to do back in the day at Purdue.  I used to use the logical flags for errors and  collect the current environment as a key,value pair (key="error", value=environment()) and in that way I knew exactly what the problem was.  I forgot until this moment =)

you can also try , debug='collect', though the new RHIPE i hear has a nice debug feature. Ryan has more information
