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

Hi Andy and Gabor,
Thanks for your help so far! I am discovering another R dimension.
Trying to put my head around all this....the conflict actually exposes
itself when calling summarize(Hmisc). Summarize(Hmisc) calls label
internally, so I can not call it explicitly. Simply calling
label(xtable) explicitly will not solve the problem with summarize(Hmisc).
Thus, I should use namespaces as Andy is suggesting. Now I just need to
know how I 'add namespace' to a library? Does 'loadNamespace' have
something to do with it?
Thanks very much for your help!
Sander.

npk <- data.frame(block=gl(6,4), N=factor(N), P=factor(P),
K=factor(K), yield=yield)
## to show the effects of re-ordering terms contrast the two fits
tmpAov <- aov(yield ~ block + N * P + K, npk)
tmpTable <- xtable(tmpAov , caption="Test export of ANOVA table.",
label="tab:Anova")
print.xtable(tmpTable, type="latex", floating=TRUE,
table.placement="h", caption.placement="top",
latex.environments=c("center"))
Alternatively, using namespace for xtable:
tmpTable <- xtable(tmpAov , caption="Test export of ANOVA table.")
xtable:::label(tmpTable) <- paste("tab:Anova")
print.xtable(tmpTable, type="latex", floating=TRUE,
table.placement="ht", caption.placement="top",
latex.environments=c("center"))
