Problems with R package building

Hi,

    Following your advice, I install R tools from
http://cran.r-project.org/bin/windows/Rtools/
Rtools215.exe <http://cran.r-project.org/bin/windows/Rtools/Rtools215.exe>

    Files are automatically installed here:
C:\Rtools

I run the code again and get the message

Creating directories ...
Error in package.skeleton(list = c("f", "g", "d", "e"), name = "test1pkg",
  :
   directory 'D:/R/pkgtest/test1pkg' already exists

R CMD build test1pkg

Error: unexpected symbol in "R CMD"

    Is there anything else I need to do ?

Miao

Hi,

  I try to build a toy package by running the following codes in an R
program

require(stats)
f <- function(x,y) x+y
g <- function(x,y) x-y
d <- data.frame(a=1, b=2)
e <- rnorm(1000)
package.skeleton(list=c("f","g","d","e"), name="test1pkg",
path="D:/R/pkgtest")

   Then the program runs smoothly

Creating directories ...
Creating DESCRIPTION ...
Creating NAMESPACE ...
Creating Read-and-delete-me ...
Saving functions and data ...
Making help files ...
Done.
Further steps are described in

'D:/R/pkgtest/test1pkg/Read-and-delete-me'.

    Since it is a test, I skip all the documentation work and then type
this line:

R CMD build test1pkg

Error: unexpected symbol in "R CMD"

   I check on the web about the error message. It's said that the command
should be typed in a DOS window (command prompt window?). However it does
not work  in my DOS window either. Could someone tell me how to process

the

package building process?

Have you installed the Windows Rtools from CRAN and made sure your PATH is
set properly?

   Thanks,
