[R] about the char _

[Gerard.Keogh@cso.ie]

Yes I agree with Fan. For those of us (new to R and) who also use SAS, the
underscore is an ideal way to create variable names. In fact it provides a
good convention for naming global variables in code that is written to be
called by  say another "users" program. R's use of the "." to concatenate
names is useful to distinguish variable levels but I think that being able
to name an object  _myfun.x1 would be a great asset in future versions of
R.

Dear all,

I don't know the historical reason why the char '_' was
defined in the R language grammar as a synonyme of the
assignment <-, anyway the R documentation dosen't recommand
its usage.

Well, this is a real "incompatibility issue" each time
we need to interface R with other language/systems, notably with
database systems. Recall that, in perhaps all computer systems,
the char '_' can be used in the name of a variable or a column
in a data table.

So that's my question : is there an option to change this
behaviour ?

All that I want is the possibility to use the same name of
variables in my R source as they are declared in the other systems.

Thanks
