R help - Nov 2006 - problem with source(), parse() and "french" colnames

Hello every one

Working under Windows Xp in French, and R version 2.4.0 (and : >
localeToCharset()  :  "ISO8859-1" )
I am trying to source a file with basic commands.

source("R files/InputFile Analysis (Calculs et mises à l'échelle -
gestion
des pb d'unités).r")

and it works fine as long as I do not use command like these ones :

file_table[[2]]$MES.boue.recirculée.autosurveillance   <-
1000*file_table[[2]]$MES.boue.recirculée.autosurveillance
file_table[[2]]$MES.boue.recirculée.en.continu           <-
1000*file_table[[2]]$MES.boue.recirculée.en.continu

These commands work perfectly when used individually and submitted directly.
But when I am sourcing the command file including these lines, I get the
following error message :

Erreur dans parse(file, n = -1, NULL, "?") : erreur de syntaxe à la
ligne
35: MES.liqueur.mixte.en.continu<-
1000*file_table[[2]]$MES.liqueur.mixte.en.continu
36:     file_table[[2]]$MES.boue.recircul‚

I guess that the problem is coming form the "é" in my colnames as the
following command :

file_table[[2]]$MES.liqueur.mixte.autosurveillance<-
1000*file_table[[2]]$MES.liqueur.mixte.autosurveillance

works fine, even when sourced ...

My colnames are make.names() output, and I am wondering how to set up things
to allow "é" in sourced commands (or enventually to transform
"é" in "e"
with mae.names).
Does any body know how ?

Thanks, and sincerely yours,

Pascal Boisson

I am unable to reproduce this.  Note that source() makes use of 
options("encoding"), and that should be
> options("encoding")
$encoding
[1] "native.enc"

I do get a problem with e.g. source("foo.R",
encoding="ASCII")

If that is not the problem, please produce a small reproducible example 
that fails when run with Rterm.exe --vanilla. As the footer of every 
message says:

(and that asks you not to send HTML mail).
