Dear list members,

I use the package inlinedocs to create documentation for a package that I am building. The function package.skeleton.dx() is used to convert the source *.R file into the *.Rd documentation file. Usually this works like a charm, but on several occasions I got messages like this one:



extra.code.docs prefixed.lines extract.xxx.chunks title.from.firstline examples.from.testfile definition.from.source edit.package.file author.from.description erase.format title.from.name examples.in.attr collapse tag.s3methods
Creating directories ...
Creating DESCRIPTION ...
Creating Read-and-delete-me ...
Copying code files ...
Making help files ...
Done.
Further steps are described in './spectral.methods/Read-and-delete-me'.
Modifying files automatically generated by package.skeleton:
add.axis: definition title description item{side} item{trans.fun} item{label} item{\dots} seealso author format best.iter.default: definition description item{perf.matrix} details seealso author value format title
determine.freq: title description item{series} item{plot.periodogram}

<long list of the functions in my package>
...

Warning message:
In grep(prefix, src) : input string 65 is invalid in this locale


The warning message, however, gives me no hint on in which file and in which position (maybe line 65?) the invalid string can be found. On some occasions I was able to manually find these strings because I remembered which file I recently worked on. One of such errors was for example caused by a í instead of a i (can you see the difference?). Additionally I have the impression that an error is caused while using R-2.10 and only a warning is caused with 2-12.

Is there any convenient way of finding out where exactly this erroneous string is? I tried to execute package.skeleton.dx() row wise but the function quickly branches into a complex nesting of other functions.



Thanks for any advice!

Jannis
