Not quite:

1. It's not Hmisc, it's survival, which Hmisc uses.

2. If you have 'sampling' loaded and then load 'survival', you get a warning
The following object(s) are masked from ‘package:sampling’:

    cluster, strata

Similarly, if you have 'survival' loaded and then load 'sampling', you
get a warning
The following object(s) are masked from ‘package:survival’:

    cluster, strata

The warning tells you that two packages have defined cluster() and
strata() functions, and which one is currently the default.
