build R pacakge for windows -ERROR: compilation failed for package xxx -

i having trouble build dummy testing package r on windows. testing purpose,in r terminal, input:

a=rnorm(10) package.skeleton("pkgtest") 

then run r cmd check pkgtest on dummy package , got error like

* using r version 2.12.0 (2010-10-15) * using platform: i386-pc-mingw32 (32-bit) * using session charset: iso8859-1 * checking file 'pkgtest/description' ... ok * checking extension type ... package * package 'pkgtest' version '1.0' * checking package dependencies ... ok * checking if source package ... ok * checking executable files ... ok * checking whether package 'pkgtest' can installed ... error installation failed. 

edit,the full log file:

* installing *source* package 'pkgtest' ... ** libs cygwin warning:   ms-dos style path detected: c:/r/r-212~1.0/etc/i386/makeconf   preferred posix equivalent is: /cygdrive/c/r/r-212~1.0/etc/i386/makeconf   cygwin environment variable option "nodosfilewarning" turns off warning.   consult user's guide more details posix paths:     http://cygwin.com/cygwin-ug-net/using.html#using-pathnames error: compilation failed package 'pkgtest' `* removing 'c:/docume~1/xxxx'`  

that all. have data a in data folder, not empty. rd file can compile pdf rcmd rd2pdf, title not empty.

did missing basic error? have rtools2.12 installed. have package inline , rcpp intalled , running examples fine. test r environment setup, downloaded rcpp source package , did r cmd check on rcpp, went fine.

yes, lot if did steps documented above.

firstly, did output package.skeleton asks to?:

> a=rnorm(10) > package.skeleton("pkgtest") creating directories ... creating description ... creating read-and-delete-me ... saving functions , data ... making files ... done. further steps described in './pkgtest/read-and-delete-me'. 

in particular last line.

you don't quote full check log, get:

$ r cmd check pkgtest * checking working pdflatex ... ok * using log directory '/home/gavin/tmp/pkgtest.rcheck' * using r version 2.11.1 patched (2010-08-17 r52767) * using session charset: utf-8 * checking file 'pkgtest/description' ... ok * checking extension type ... package * package 'pkgtest' version '1.0' * checking package dependencies ... ok * checking if source package ... ok * checking executable files ... ok * checking whether package 'pkgtest' can installed ... error installation failed. see '/home/gavin/tmp/pkgtest.rcheck/00install.out' details. 

so should go , check contents of .out file mentions. have following in file:

$ cat /home/gavin/tmp/pkgtest.rcheck/00install.out * install options ' --no-html'  * installing *source* package ‘pkgtest’ ... ** r ** data ** preparing package lazy loading ** warning: ./man/pkgtest-package.rd:34: text must in section warning: ./man/pkgtest-package.rd:35: text must in section *** installing indices error in rd_info(db[[i]]) :    rd files must have non-empty \title. see chapter 'writing r documentation' in manual 'writing r extensions'. * removing ‘/home/gavin/tmp/pkgtest.rcheck/pkgtest’ 

which self-explanatory, once @ package source.

you needed @ least:

> a=rnorm(10) > package.skeleton(name = "pkgtest", list = "a") 

and should note have edit rd files. design feature prompt() , package.skeleton() not create valid rd files package authors write minimum documentation packages.
