[Rcpp-devel] CRLF to LF warning

Hi,

I'm a windows user and I'm trying to make a package using 
Rcpp.package.skeleton.  When I check my package using R CMD check, I get 
the warning:
Found the following sources/headers with CR or CRLF line endings:
   src/rcpp_hello_world.h
Some Unix compilers require LF line endings.

I get this warning even when produce a package skeleton using the 
following code:
library(Rcpp)
Rcpp.package.skeleton("m1p")

I get more files having this issue, including .cpp files when I start 
editing them with Notepad, Wordpad or RStudio.

I'm not sure how to fix this problem, I've tried to use the following 
command in Command Prompt:
tr -d '\r' < rcpp_hello_world.h >> rcpp_hello_world.h

But it's not quite working.

I'm not sure whether I can ignore this warning or not, especially since 
I will use my package on a Unix machine.

Many thanks,

Marie
