I don't understand that statement - locate looks in an index, based on
the whole file system (more or less), whereas R looks in specific
locations ($HOME and certain other directories dependant on the
installation directory of R.

Well - a "find" on a complete HDD takes some time. Furthermore I just
realised that "locate" is case sensitive, and find too. So "find -name
"*.rData" will not find the .Rdata file ... Just something to keep in mind.

Absolutely - But I had exactly the same problem after installing rattle,
but as I usually use --vanilla, it did not affect me that much. It took
me quite some time to figure out what was happening. This raises the
question, if R should not have a "fallback" mechanism, so that at least
the other data in an Rdata file could be read (obviously giving a HUGE
warning!)
