Dear Terry,
One way to locate which file is wrong - surely not the most brillant
way! You could do an R script that sources each of your .R files within
a "for (file in file.names)" loop.
When R will stop, it will indicate which file has a wrong syntax and
more info.
Cheers,
Mathieu

I'm making the move of the survival package from my own environment to,
and have stumbled into a vacuum. The R Extensions manual has really nice
instructions about how to lay out the directories, order the files, and
run tests for DISTRIBUTION of a product, but I can't find anything on how
to set up a reasonable DEVELOPMENT environment.
In my local world, I had the .c and .s files in a common directory, with
a Makefile that I had created, and the test suite in a subdirectory. Debugging
and development was quite nice.
make
cd test
R
attach("..")
try something and perhaps it fails
q()
cd ..
Fix and repeat. The Makefile took some time to create, but paid for itself a
hundred times over.
So, I've now rearranged everything into standard R order. Then I did the
only thing I could find
R CMD INSTALL ~/myRlib survival
where "survival" is said directory. This turns out to be not useful at all.
The survival package is large, and I rather suspected that I would goof
something up, and I did, resulting in the following message
Error in parse(n = -1, file = file) : unexpected end of input at
14450: }
14451:
It is not exactly obvious which of the 132 files in my R/ directory is the
culprit here.
In general:
1. The library is large, and recompiling/reparsing everything is very far from
instantaneous. It is not the edit/load cycle I desire.
2. I take testing seriously: the test suite takes on the order of 15 minutes to
run on a fast machine. I most certainly don't want to run it in the mid cycle.
Someone must have tackled this. I'm hoping that there is some documentation
that I have managed to overlook which discussess a good setup for this middle
ground between concieving of a library and packaging it for delivery; the
"build, test, make sure it acually works" part of development.
