I wanted to do a simple plot: Death Rate vs Clinical Site, and then draw a confidence interval of Death Rate at each clinical site, which is a factor variable with 100 levels. I used the following code: plot(Site, Rate, col="red", type="o") However, the graph was a short line at each site instead of points, and the color was not red at all. Seem to me for factor variable all

Right now, if I run: beorun --nolocal R I just get the R start-up message and back to the shell prompt. If I try bpsh 0 R I can get R started (but the R prompt does not

...Kevin Boyd made RsyncX and rsync_hfs, to address this gap, but they only work when the destination filesystem is also HFS+. I haven't been able to find any references to an rsync that is capable of syncing from HFS+ to UFS (etc). The only solutions I've seen involve lots of preprocessing chicanery and additional disk space consumption (basically, dupe the resource forks or entire files first, then copy them over), which doesn't suit my needs. So I'm working on a patch to the mainline of rsync-2.6.0 that will recognize a resource fork on an HFS+ filesystem, and copy the data to a sep...
