[R] Namespace support?

[Nunoo, Paa K]

Hi,
I have created an R package in which I implement my own version of the
"as.dataframe" function. However when I load up my package into R, it seems
to mask the original version of "as.data.frame". Is there to limit/control
the scope of the "as.data.frame" function defined in the my package so that
it does not interfere with the original function? Maybe by using namespaces
in R?

thanks
