Hello everyone, I need to do k-medoids clustering for data which consists of 50,000 observations. I have computed distances between the observations separately and tried to use those with pam(). I got the "cannot allocate vector of length" error and I realize this job is too memory intensive. I am at a bit of a loss on what to do at this point. I can't use clara(), because I

.... Would value.labels or vallabs create conflicts? The attribute should be structured as data.frame with two columns, levels (numeric) and labels (character). These could then also be used to transform from numeric to factor. If the attribute is copied to the factor variable it could also serve to retransform the factor to the original numerical variable.

R-Experts: Does anyone know if there are R functions to perform the Freeman-Tukey double arcsine transformation and then backtransform it? Thanks, Brant Inman Mayo Clinic

I spent some time this week trying to add support for input transformations to the server. I tried a few different approaches. The patches I've attached are what's currently working best for me. In this approach I allow every window to have it's own root window coordinate space. A window's root window coordinate space is affected by all it's ancestors. Composite clients can
