[Tal Galili]

Hi Deivit,
Can you offer a self contained example of r code when the function fails
for you?

 Hi all,

 Since three month ago I started working with R professionally, I never did
 it before, so I am such a newbie.
 I am having some problems using the 'debug' package. I love this package,
 but most of the times I wanna use it it just fails :P

 When typing at prompt 'mtrace(myfunct)' most of the times I get the
 following error:
 Error in x[[i]] : subscript out of bounds

 I can't understand whats happening and I couldn't find any help surfing the
 net. I have the feeling it might be because of my coding style or something
 similar.

 Any help will be highly appreciated :)

 Thanks in advance!
 see ya

Re: [R] debug package: mtrace fails

[deivit]

I'll try,

Here is a piece of code it fails for me, the error I get is always the same,
and it happens in most of my functions. The problem is always the same
trying to execute 'mtrace'.

Thanks!

--- execution --

 mtrace(index_remap)
Error in x[[i]] : subscript out of bounds

--- code ---

index_remap - function (idx_relation=NULL, idx_vector=NULL, undo=FALSE)
{
if ((! any(duplicated(idx_vector)))  all(idx_vector %in%
idx_relation))
{
updated_idx - {}
for ( i in 1:length(idx_vector) )
{
if (undo == FALSE)
{
updated_idx - c(updated_idx, which
(idx_relation == idx_vector[i]))
} else {
updated_idx - c(updated_idx,
idx_relation[idx_vector[i]])
}
}

return (updated_idx)
} else {
error_msg(Some error message)
}
}

error_msg = function ( msg=NULL)
{
cat(style(msg,fg=red),\n)
}
