Changing a directory to a symlink; rsync balks.
Good day, all, I'm using rsync 2.5.4 and a statically linked version of 2.5.5 to back up my main system to a backup drive (See rsync-backup at http://www.stearns.org/rsync-backup/ ). First, I made a full backup of the system. Then, on the main system, I merged the articles in techdocs to another directory called articles, removed the techdocs directory and made it a symlink to the articles directory. Then I performed another backup. I get: delete_file: rmdir(home/wstearns/med/techdocs) : Directory not empty rsync: symlink "home/wstearns/med/techdocs" -> "...

return first index for each unique value in a vector
...,5,9) but also their first indices (2,4,1). I tried using a for loop with which(A==unique(A)[i])[1] to find the first index of each unique value but it is very slow. What I am trying to do is easily and quickly done with the "unique" function in MATLAB (see http://www.mathworks.com/help/techdoc/ref/unique.html). Thank you for your help, Bronwyn [[alternative HTML version deleted]]

can I draw 3D plot like this using R?
hi, all I am looking at R package RGL to draw a colored mesh/surface plot like this one (from matlab). http://www.mathworks.com/access/helpdesk/help/techdoc/visualize/cbar.gif The key features I am looking for is surfaced with grid and color, but not the terrain-like gradient. but I didn't come even close to it after browsing through rgl help file. have anyone drawn something like this before, is this doable afterall? thanks Oliver

OT: AF 4k sector drives with 512 emulation
Still have good quality older sata hardware raid cards that require 512 bytes/sector. As far as I know HD manufacturers are not making native 512 bytes/sector drives any more. Some have better 512e emulation than others. Looking for some advice on which to avoid and which are recommended. Thanks. PS this is for a CentOS6 server.

calculating the mode in R...
Dear R users I?m aware that the package ?modest? is useful to find the mode in an array. However, I?d like to know if someone has translated the ?mode? function built-in in MATLAB into R language. This function finds the most frequent value in an array (http://www.mathworks.com/help/techdoc/ref/mode.html). Best Fer

Sector size on 7K3000 drives?
Hi al Does anyone here that knows if the new 7K3000 drives from Hitachi uses 4k sectors or not? The docs say "Sector size (variable, Bytes/sector): 512", but since it''s variable, any idea what it might be? I''m planning to replace 7x3+1 drives on this system to try to get some free space on some full VDEVs. If the drives are in fact 4k sector drives, will it be possible

R analog of Matlab "eigs" function
Hi, I was wondering if anyone knew of an implementation of a function similar to "eigs" in Matlab (full description here: http://www.mathworks.com/access/helpdesk/help/techdoc/ref/eigs.html). This function differs from the standard "eigen" in that it computes a *few* eigenvectors for cases in which your matrix is very large and/or you don't need all the eigenvectors. (It uses the Arnoldi-Lanczos iterative method, as implemented in C in ARPACK). For exampl...

Code behind the Function
Hi, I am a new user in R. I wanted to study the code for some R commands. For example, as I was studying PCA analysis there is a command in R, as "princomp". Normally if we type the command we get the code behind the function, but I am not able to get for this one. *> princomp function (x, ...)

Serial PnP for NUT?
Are there any plans for using serial PnP in NUT? I tried to implement this on the 'safenet' driver, but the support for this doesn't seem to be widespread among the UPSes compatible with this driver. So far, I have only managed to get one (a Sweex 1000) to output it, but unfortunately, it is probably too generic to be really useful for autodetection: PnP revision : 1.00 PnP EISA ID
