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.

I feel this is an xtable problem because Hmisc has being using label and label<- since 1991.
