[R] invalid strings while parsing code with inlinedocs package.skeleton.dx()

[Jannis]

Seems as whether I found a (clumsy) workaround:

1. options(warn =2)
2. run package.skeleton.dx, now an error is produced with the name of 
the file package.skeleton was actually working on
3. The number of the erroneous input string should correspond to the 
line number in that file.

Just in case anybody is digging for the same solution ;-)
