[R] Conflict between xtable and Hmisc when using Sweave?

Dear R users,

The Sweave code below runs fine, as it is. However, an error occurs when 
the line 'library(xtable)' is uncommented:
Error:  chunk 1
Error in "label<-"(`*tmp*`, value = "month") :
         no applicable method for "label<-"

Is anybody aware of this and knows a workaround?

Thanks,

Sander.
