Hi the list,
I define a method that want to change an object without assignation
(foo(x) and not x<-foo(x)) using deparse and assign.
But when the argument of the method does not match *exactly* with the
definition of the generic function, assign does not work...
Anything wrong?

I have had some comments on sqldf regarding its dependence on tcltk
such as the second last sentence on this blog post:

R can be built without tcl/tk and so I think it would still be good to
check at runtime.

If I recall correctly, I thought indexing a vector/list with a
character vector uses hashing if the vector is over a certain length
(I can't remember the cutoff). Otherwise, it's a linear operation.

to see the difference between the two functions, and this will explain
their different behaviour. This feature of S4 has been discussed here
many times before, see e.g.:

when I try to make a package coping R code such as tab1, summ, titleString,
setTitle from epicalc package, the following problems are found.
* using log directory 'C:/Rpackage/EpiStat.Rcheck'
* using R version 2.10.0 (2009-10-26)
* using session charset: ISO8859-1
* checking for file 'EpiStat/DES
Hi,
First thing to observe is that you are calling RSymbReg via .Call, but
that function does not return SEXP as is required by the .Call interface.

Thank you so much! Although the memory leak is still there after the fix you
suggested, gdb is giving me better outputs and I believe I can trace the
memory leak origin.

I think I have a fix that avoids the problem by just growing the
vector as necessary as the directory is traversed (and no longer uses
count_lines()).
I don't have access to the code at the moment, but I should be able to
post the patch tomorrow. Is there interest in my patch?
