Hi list, not really a problem to solve but a strange unwanted behavior (at least I do not like it): I'm loading library(multiv) to use sammon. Later I load library(MASS) which tells me that sammon is masked now, because there is also a MASS version of sammon. Since I believe that the MASS version is at least as good as the multiv version, I would also use the MASS version, but help(sammon) still gives the help page for multiv's sammon. The MASS version runs, though (and gives an error if I call it like I would call the multiv version with dimension called p instead of k). Is it a general behavior that if a function is masked, the help page still is the old one? That would not be too user friendly...

I get the sammon help from MASS when I do that in 1.8.1 and 1.9.0, and that is the design. I suspect your version of MASS is not installed properly. If you just do library(MASS) help(sammon) do you get any help for sammon?

Hi, Martin Maechler told me that the following is an ESS and not an R-problem, which can be solved (inside ESS) by C-u C-h C-v sammon Outside ESS, the problem does not occur (which I had not tried out before).
