[R] dump.frames, debugger and the "..." argument

[Jannis]

Well, its 2.10, a slightly old version. I know that I am advised to upgrade to the current version. Unfortunately the installed version on the machine I am using is out of my reach. The reproducible example would be:

dummyFunct = function(a, ...) {
  b = 2* a
  c = d           # should cause error
  return(b)
}

options(error = quote(dump.frames(dumpto = "last.dump", to.file = TRUE)))

dummyFunct(1)
load("last.dump.rda")
debugger(last.dump)
# selection of call 1 causes:

# Error in get(.obj, envir = dump[[.selection]]) : 
#  argument "..." is missing, with no default




R version 2.10.1 (2009-12-14) 
x86_64-unknown-linux-gnu    

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     

loaded via a namespace (and not attached):
