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

One possible solution without renaming the functions is to add namespace to either xtable or Hmisc. Given the size of Hmisc, it probably would be much easier to do that with xtable.

With namespace in xtable, you can do xtable:::label() to refer to the label() in xtable specifically.
