Hello.
I've developed an algorithm in R which I need to package.
The implementation uses S4 objects and it's divided in 5 files.
Everything is working fine when I load the files into the R console but when
I try to make a package I get an error that I don't quite understand.
Here's what I do:
*1.* in R console, I do and get:
> package.skeleton(name='remora')
Creating directories ...
Creating DESCRIPTION ...
Creating Read-and-delete-me ...
Saving functions and data ...
Making help files ...
Done.
Further steps are described in './remora/Read-and-delete-me'.
Warning messages:
1: In dump(internalObjs, file = file.path(code_dir,
sprintf("%s-internal.R", :
deparse of an S4 object will not be
source()able
2: In dump(internalObjs, file = file.path(code_dir,
sprintf("%s-internal.R", :
deparse of an S4 object will not be
source()able
3: In dump(internalObjs, file = file.path(code_dir,
sprintf("%s-internal.R", :
deparse of an S4 object will not be
source()able
4: In dump(internalObjs, file = file.path(code_dir,
sprintf("%s-internal.R", :
deparse of an S4 object will not be source()able
I don't know why I get these warnings. I've followed R implementation rules
and the S4 objects work fine.
*2.* Performing the 'R CMD build remora' command I get:
* checking for file 'remora/DESCRIPTION' ... OK
* preparing 'remora':
* checking DESCRIPTION meta-information ... OK
* removing junk files
* checking for LF line-endings in source and make files
* checking for empty or unneeded directories
* building 'remora_1.0.tar.gz'
And the remora_1.0.tar.gz file seems ok.
*
3.* Performing the 'R CMD check remora' command I get:
* checking for working pdflatex ...sh: pdflatex: not found

NO

I'm using R version 2.8.1 (2008-12-22).
Sorry for the long email, but I don't want to miss any important
information.
Am I doing something wrong? If so, what?
How can I overcome this problem?
Thank you very much.
