how to store estimates results as scalars of a matrix?
Dear R users, I've written a loop to generate Moran's test (spdep package) on serval subsamples of a large dataset. See below a short example. My loop is working fine, however I would like to be able to store the test results as lines of a matrix, that I would latter be able to export as a dataset. My problem is that I'm not sure how I could do this using R. Any help will be much

Problem installing RCS on SXCE
I was shocked to find no RCS on SXCE 107. I needed it to update some RCS archives I had copied over. No problem - go to sunfreeware and copy it over. No OpenSolaris branch? The Solaris 10 package should work. Only the package install appears to complete and does not - as documented only in a log file, not on my screen. OK then, the source for RCS should be easily compiled and installed, I

A Question on lowess() function
Hi, all, I want to use lowess(x, y) where x and y are vectors of length of 4000+. In fact, x and y are log of some vectors. So, some of the elements are NaN. lowess() can not take away those elements then do the fitting. It will give the error message and do nothing. 1. Can anybody tell me how to get rid of those NaN's and use lowess()? 2. How to get the LOWESS fitting values for any

Generate "Compiled catalog"/yaml for a node?
Hi Experts, I remember we had this discussion before, but could find it. Can I run a command to generate a "Compiled catalog" for a specific node (on the master node)? And apply this on the client node? What are the limitations for doing this? Basically we have special handling for the webserver/CA part of puppet. Thank you very much! -Yushu
