...ugh complaining about dependencies. Do all the listed rpm files need to be installed? What is the order in which these need to be installed? I appreciate any help with this or any suggestions for alternate ways for installing pre-compiled versions of R and the packages in RHL. Thanks. -Christos Hatzis

Hello, Could someone recommend a good book on regular expressions with focus on applications/use as it might relate to R. I remember there was a mention of such a reference book recently, but I could not locate that message on the archive.

The S Programming book mentions that a library Rdll.lib needs to be built from source, but I am not sure if this is still the recommended route.

On the firewall, what is the rationale for giving eth1 an IP address that is also assigned eto eth0? (Rather than a private one.) -- Taso Hatzi caesar 17 <<-salad cjbx jc vdwwjar jc xi jc jd salad

Environment is Samba as a PDC, OpenLDAP backend, with smbldap-tools providing the scripts to manipulate the data. What are the recommended/mandated organizational units (OU=) for user, computer, group info. I'm pretty sure that groups go in ou=Groups, but I am confused about where user and computer data goes. I have seen ou=People, ou=Computers, and ou=Users in various places. Which is it

This is some ramblings on why using proxy ARP (on a host in a DMZ) is a good or bad thing. The good is that a computer X retains a public IP address which makes it easy to connect it directly to the net if the firewall has to be taken down for extended periods. Thus, if computer X is a mail server for example, it can still function in a reduced capacity until the firewall is restored. The bad

There has been a low continuing level of confusion over the terms "Source NAT" (SNAT) and "Static NAT". To avoid future confusion, all instances of "Static NAT" have been replaced with "One-to-one NAT" on the web site and in the CVS configuration files (Shorewall/ project). The documentation in 1.4.9 will also contain this change. -Tom -- Tom Eastep \

The problem scenario I describe was reported previously in the Shorewall lists but its resolution does not seem to have made it into the lists. Scenario: Windows XP client seeking to establish a VPN connection to a Windows 2003 Server located behind a Shorewall firewall (running on Mandrake kernel 2.4.22-37mdk). The connection cannot be made, the client reports error code 721. Discussion:

Dear altogether, I want to blank the lower (or upper) part of a correlation matrix as it is done by dist() example: ( d <- cor(matrix(runif(12),nrow=4)) ) If I do the following d[lower.tri(d)] <- "" of course everything is changed to character - that's not what should be. Additionally, it does not work to assign "0" or anything else. The same is true for

...the .C interface. Is there a way this can be done with .C? I suspect it will use in some way the "vector of pointers to row vectors" concept, but I am not familiar enough in C yet to figure it out. Any hints on how in can be done with .Call if easier?

Are there any scenarios that require traffic from a zone to itself to be blocked? If not, Shorewall should possibly allow it as a matter of course. It seems strange having to explicitly create such a policy & it''s not immediately obvious when it is required. -- Taso Hatzi caesar 17 <<-salad cjbx jc vdwwjar jc xi jc jd salad
