[BioC] conflict between ROC and Hmisc or Design?

[Shi, Tao]

Hi list, 
 
 I found that I can't load 'ROC' after 'Hmisc' or 'Design' have been loaded.  It works the other way around.  Do you know why?   From the error message, it seems the problem is in 'Biobase'....

thanks,

...Tao


> library(Hmisc)
Hmisc library by Frank E Harrell Jr

Type library(help='Hmisc'), ?Overview, or ?Hmisc.Overview')
to see overall documentation.

NOTE:Hmisc no longer redefines [.factor to drop unused levels when
subsetting.  To get the old behavior of Hmisc type dropUnusedLevels().

Attaching package: 'Hmisc'


        The following object(s) are masked from package:stats :
