[R] ERROR: unable to collate and parse R files

[Christian Hoffmann]

I tried in vain to execute

R CMD  install /Users/hoffmann/R/cwhmisc  ('cwhmisc' is the package name)

* installing to library 
‘/Library/Frameworks/R.framework/Versions/3.2/Resources/library’
* installing *source* package ‘cwhmisc’ ...
** R
Error : '\&' ist eine unbekannte Escape-Sequenz in der Zeichenkette 
beginnend mit ""\&"
ERROR: unable to collate and parse R files for package ‘cwhmisc’
* removing 
‘/Library/Frameworks/R.framework/Versions/3.2/Resources/library/cwhmisc’
* restoring previous 
‘/Library/Frameworks/R.framework/Versions/3.2/Resources/library/cwhmisc’

Strategy of mine:
- search the net :
- grep for '\&'  : to no avail
- remove ~/.Rprofile : no success (it contained only 
'options(repos=c(CRAN="http://stat.ethz.ch/CRAN/"))' anyway)
- change CRAN mirror in .Rprofile : no success
- check vignette : nothing

- R CMD  check --as-cran /Users/hoffmann/R/cwhmisc : Installation failed.
   00install.out reads (also) Error : '\&' is an unrecognized escape in 
character string starting ""\&"
ERROR: unable to collate and parse R files for package 'cwhmisc'

What could be a way out of this maze?
