Its coming from the Hmisc startup. For example, in a clean session (R
--vanilla) try this:
library(survival)
library(Hmisc)
Replacing the above call with this will suppress it:
suppressPackageStartupMessages(library(Hmisc))
To track it down:
debug(message)
and then run your script and step through each line in the debugger
until you see the message and then enter:
sys.calls()
to see where you are.
