| Of course, I installed Rtools 2.12.

Very good!
 
| Q2) Have you ever compiled an R package from source on Windows?
| Yes. Before compiling the package "mypackage"  in the Windows Command Prompt, I
| opened the package from Eclipse as a project, and I ran its R function in R
| console as follows.

Just to be on the safe side, please download a simple package from CRAN---my
small 'digest' package at http://cran.r-project.org/web/packages/digest/index.html
would do---to 'prove' that you can build a package containing C code. We should
get that step out of the way.

| But, nothing happened. Thus, I tried to build a package from the skeleton.
| 
| Q3) the command you executed
| Please, refer to the above answer.
| 
| Q4) the errors you got
| In the Windows Command Prompt, I had the following error message.
| 
| > R CMD build mypackage
| checking for file 'mypackage/DESCRIPTION' ... OK
| preparing 'mypackage':
| checking DESCRIPTION meta-information ... OK
| cleaning src
| ERROR
| copying to build directory failed
| 
| Also, a popup window opened with the error message "the operation of 'make.exe'
| was stopped."
| Then, it suggested to refer the following files, but I could not find them in
| the specified folder.
| 
| \AppData\Local\Temp\WER9159.tmp.WERInternalMetadata.xml
| \AppData\Local\Temp\WER9D1D.tmp.appcompat.txt
| \AppData\Local\Temp\WERA078.tmp.mdmp

That looks like some arcane Windows errors. 

I can be of no help here, but maybe someone else can.

| rcpp_hello_world <- function(){

| }
| 
| -- rcpp_hello_world.cpp
| 
| #include "rcpp_hello_world.h"
| 
| SEXP rcpp_hello_world(){
|      using namespace Rcpp;
|      CharacterVector x = CharacterVector::create( "foo", "bar" )  ;
|      NumericVector y   = NumericVector::create( 0.0, 1.0 ) ;
|      List z            = List::create( x, y ) ;    
|      return z ;     
| }

|     We do not have mind readers.  So unless you show us
| 
|       i)   the command you executed
| 
|       ii)  the errors you got
|
