[R] Unexpected call to "require"

[Dennis Fisher]

Colleagues

I am executing a length script in R (20K lines).  At one point, it returns:
> Loading required package: tcltk
> Loading Tcl/Tk interface ... done
> Loading required package: Hmisc
> Loading required package: survival
> Loading required package: stats
> Loading required package: graphics
> Loading required package: splines
> Attaching package: 'Hmisc'
> 	The following object(s) are masked from package:survival :
> 	 untangle.specials 
> 	The following object(s) are masked from package:base :
> 	 format.pval,
> 	 round.POSIXt,
> 	 trunc.POSIXt,
> 	 units 
> Loading required package: R2HTML

This is not a problem but I am curious as to the source of the message.

The command "require" appears three times in my code, for chron, XML, and SASxport.  When I test each of these (e.g., require("chron")) in a new session of R, I don't receive the messages shown above.  But, the script does return that message.

Does anyone recognize this specific message, i.e., what is triggering the messages?

Thanks in advance.

Dennis
