[R] error preparing a package for lazy loading with R CMD

[Patrick Giraudoux H]

That's the way John Fox advised to turn the problem. Indeed it works but 
doe snot explain this bug in lazy loading. I don't think that it may come 
for a syntax error somewhere. All the functions have been checked and the 
problem does not occur if any of the 35 functions is removed. Something 
happens when I add another function to the 34 already present. Strange.
