Yet, when I try to use it, I get something incomprehensible:

Error in str(NLSY) : internal error -3 in R_decompress1
In addition: Warning message:

That usually means that the LazyData database has been corrupted (and
most likely was not created properly). As to why: we need the
reproducible example the posting guide asked you to provide.
But it works if I load directly from the file I imported into the package:
> load("NLSY.RData")
> str(NLSY)

What could cause this?
