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

What makes you think this qualifies as "editing"? Please read the Writing R Extensions manual thoroughly. If you had, you would see that what you have written will clearly not work (though I would think this intuitively obvious if you have ever read documentation for R...what function is simply documented, "A function."?). Here is a link to the manual: http://cran.r-project.org/doc/manuals/R-exts.html it actually provides a wealth of information and when I was writing my first package, I kept it open and constantly referred to it as I was writing documentation, naming files, creating the DESCRIPTION file, etc. The other resource that helped me tremendously was Dr. Chambers book Software for Data Analysis. You might also consider downloading the source code for a package (I just used the SoDA package) so you have an example of how someone who knows what they are doing writes a package. I feel pretty strongly that: "I strongly feel that related documentations should be more Statistician-friendly, than some Engg. guys" is quite an unfair statement given all the time and effort R core has put not only into writing R, but making manuals and documentation that, while complex at times, are extremely thorough to the point that I, as a psychologist, with no training in computer science, engineering, or statistics, was able to blunder my way along just by carefully going through their work. Best of luck to you, Josh

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. On Wed, Jun 1, 2011 at 11:41 AM, Prof Brian Ripley <ripley at stats.ox.ac.uk> ?wrote:

?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.

?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,
