Hello list,
I'd like to know if there is a function that tells in which package is a
given function.
Something like :
which.package("lda")
[1] "MASS"
Thank you.
Romain

To search among all CRAN (and BioC) packages, your best best is RSiteSearch("fcn", restrict="function"). The result is not shown in R, though.
