Problem with package development

What else I need to do? In the Read-and-delete-me file following steps
are asked to perform:
* Edit the help file skeletons in 'man', possibly combining help files
for multiple functions.
* Edit the exports in 'NAMESPACE', and add necessary imports.
* Put any C/C++/Fortran code in 'src'.
* If you have compiled code, add a useDynLib() directive to 'NAMESPACE'.
* Run R CMD build to build the package tarball.
* Run R CMD check to check the package tarball.

I editied the help page for fn1() function (as I already communicated
in previous mail) as follows:

\name{fn1}
\alias{fn1}

\title{
A function.
}

\description{
A function.
}

\usage{
A function.
}

\arguments{
A function.
}

\value{
A function.
}

\author{
\bold{Me}
\cr
\email{Me at me.com}
}

And regarding th Namespace file, this time I put
"package.skeleton("trial1",namespace = FALSE, code_files =
"f:/trial.r")
"

I do not have any C/C++ code so I ignored 3rd step.

then Read-and-delete-me file asking me to build the package, so in
cmd, I run following:
cd C:\R_PackageBuild
Rcmd build ?binary trial1

What I am missing in this entire process? Do you please point me?

Thanks,

Thanks Prof. Ripley and Duncan for your pointers. Noting down your
points I have modified my way of building package and have done
following so far:

1. In my C: drive I create one working folder naming "R_PackageBuild"
2. In R console I have written following codes:

  setwd("c:/R_packageBuild")
  package.skeleton("trial1",namespace = TRUE, code_files = "f:/trial.r")

3. then I opened cmd and wrote following:
cd C:\R_PackageBuild
Rcmd build ?binary trial1

This process halted with following error:
Error: unexpected symbol in ?tools:::.test_load_package(?trial1?,?.)?
Execution halted
ERROR: loading failed

What I have missed in this process? Can you please help me how to
solve this issue?

You haven't done the manual changes required between steps 2 and 3.
  package.skeleton() creates the skeleton of a package; you run it once as
you are starting development, the do a lot of manual updates, described on
the ?package.skeleton help page, and in the  ?Read-and-delete-me? file.
  Once those are done, step 3 should succeed.

Thanks,

PS: I am sorry I missplet 'Program Files'. Thanks Prof. Ripley for this
pointer.

  I have been struggling for last one hour but not yet any through.

  However again I recreate the package.skeleton and run R CMD check
trial3

  Here are the errors:

  warning in dir.create(pkgoutdir, mode = "0755"):
  cannot create dir 'c:\Program files\R\R-2.13.0\bin\trial3.Rcheck',
  reason .................
  Error in printLog(Log, "", text, "\n"): object 'Log' not found
  Execution haulted

  Why I am getting this error? what is that "Log". I will really
  appreciate if somebody please help me to figure out.

  R CMD check writes a (in your case) trial3.Rcheck directory, and in
there in
  file 00check.log a copy of the log.  If it cannot create trial3.Rcheck
it
  cannot write the log.

  I would be surprised that even on Windows Vista the message was
literally

  reason .................

  but if it was, blame Microsoft for their error messages.
  But

  cannot create dir 'c:\Program files\R\R-2.13.0\bin\trial3.Rcheck',

  is clear enough.  You need to run 'R CMD check' in your user area.
  In case you did this because that is where you though 'R' was, it is
not the
  correct R.exe.   You may need to add

  c:\Program Files\R\R-2.13.0\bin\i386

  (assuming 32-bit R) to your path.

  However, your use of e.g. 'Program files' suggests you are not
accurately
  transmitting the messages you got.

  Thanks,

  Actually partly I followed. Here is the more details what I have done
so
  far:

  1. Edit the help file skeletons in 'man', possibly combining help
  files for multiple functions.
  I have modified with following:
  \name{fn1}
  \alias{fn1}

  \title{
  A function.
  }

  \description{
  A function.
  }

  \usage{
  A function.
  }

  \arguments{
  A function.
  }

  \value{
  A function.
  }

  \author{
  \bold{Me}
  \cr
  \email{Me at me.com}
  }

  2. Edit the exports in 'NAMESPACE', and add necessary imports.
  Actually I really do not know what I would do here. In the
  corresponding file, only "exportPattern("^[[:alpha:]]+")" is there.
  Therefore I put that unaltered.

  3. Put any C/C++/Fortran code in 'src'.
  I do not have any such code

  4. If you have compiled code, add a useDynLib() directive to
'NAMESPACE'.
  Again I do not know what to do, so ingored this step.

  5. Run R CMD build to build the package tarball.
  * Run R CMD check to check the package tarball.

  I did not follow this step exactly. What I done is, put 'trial3'
  folder in R/R-2.13.0bin folder (after above modification), from the
  R-working folder. Then just run R CMD INSTALL trial3. However
  previously with this job, I could create package effectively. After
  updating R to the current version my problem starts.

  Those are not sufficient?

  Thanks,

  Dear all, I am having a strage problem while I was trying to build
a
  package. Here is my package skeleton:

  fn1<- Vectorize(function(x,y,z) {
                          return(x + y +z)
                  }, vectorize.args = c("x"), SIMPLIFY = TRUE)
  package.skeleton("trial3",namespace = TRUE)

  Did you follow the instructions that package.skeleton printed?

  However when I tun "R CMD INSTALL trial3" in CMD, the execution
  stopped with following message:

  *** installing help indices
  ** building package indices...
  ** testing if install package can be loaded
  Error: unexpected symbol in
"tools:::test_load_package(.............."
  Execution haulted
  ERROR: loading failed.............

  I am using R 2.13.0 in Vista with latest Rtools installed. Can
  somebody guide me where I have done wrong?

  Thanks,
