Peter,
This is a relatively "new" warning from R CMD check (for some definition of
new). The authors of Hmisc have clearly not yet gone through the process of
cleaning it up, as you are doing right now (and there are many other
packages that still need to address this, including several of mine). Given
who the authors are of Hmisc, I would suggest writing to them and ask them
to look into this, and ask for a time estimate.
thanks for the suggestion, but I must be missing something: since
Hmisc imports survival (as well as Depends: on it), what can Hmisc
change to make the survival functionality visible to my package?
The terminology around "imports" has had many of us confused. (My copy
of) Hmisc has survival in both Imports: and Depends: in the DESCRIPTION
file (for which they will now be getting flagged) but it does not have
it in the NAMSPACE file, which it needs, whether it is in Depends: or
Imports: (and for which they are getting another flag). When this is
fixed then the Hmisc function rcorr.cens will look at its own NAMSPACE
determined path for finding functions, and find is.Surv. As Kasper
pointed out, this is not really your problem, except of course that you
need to work around the Hmisc problem. Until Hmisc is fixed, I think you
have the option of adding survival to Depends:, or leaving Hmisc in
Depends:. (I would be inclined to leave it the way you had it until
packages further down the chain are fixed.)

In the meantime, you may have to do something about this, and whatever you
do I would suggest following the Hmisc package and undo it as soon as
possible, as the right thing is to fix Hmisc. Having said that, it is not
clear to me that you can easily solve this yourself, because I don't think
that putting survival into your own imports will make the package available
to Hmisc functions, but it is not impossible there is some way around it.
Well, as I said, things work fine if I leave Hmisc in the Depends:
field, which, however, is against CRAN policy. The trouble is that I
don't have a good way of checking whether something breaks by moving a
package from Depends into Imports...
