[R] Encoding of Sweave file error message

[Duncan Mackay]

Hi

I ran the following sweave file in R2.14.1 and upgraded to R2.15 
yesterday with the same setup
I got the following error message when I rand the following Sweave file

 > setwd("D:/Cic/Sweave/Parasite/Comb/12")
 > Sweave("D:/Cic/Sweave/Parasite/Comb/12/ParasiteComb12.Rnw")
Error: c("'ParasiteComb12DS.Rnw'", "'ParasiteComb12.Rnw'") is not 
ASCII and does not declare an encoding

I checked that the files were encoded as ANSI

The file  ParasiteComb12.Rnw is a master file and sets things up and 
calls a number of Sweave files.
ParasiteComb12DS.Rnw which loads packages  processes the data is the 
first file to be called

I can run ParasiteComb12.Rnw by itself without any problems but when 
I add other files then the error message occurs.

There are no references just plain text (no extended character set) 
plain latex and R coding

The first few lines for the Sweave preamble is:

\documentclass[10pt,a4paper]{article}
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage[latin1]{inputenc}
\usepackage{times}
\usepackage{courier}
\usepackage[scaled=.92]{helvet}

I can send the files if needed as the resultant pdf that is produced 
is 42 pages.

Any pointers to solve the problem will be greatly appreciated

Regards

Duncan
