R has very good GUI packages that I have used - R Commander RCmdr and Rattle rattle . Since I work on multiple packages with constraints of time, I almost always use the GUI rather go through the intricacies of command line . The log of these GUIs shows the relevant R command that was used, so you can actually learn the language also. I have written about the ease of learning R , if you begin

I have some questions about whether I should set up folders under INBOX vs. having them outside the INBOX namespace. I'm setting up a new Dovecot 2.2.0 on an Ubuntu 12.04.2 server. My plan is to move my users (family members) to this new server from an old Cyrus server. Everybody is currently using (and will continue to use) IMAP, and either Thunderbird or SquirrelMail as their e-mail

Hi, First of all thanks for all the answers .... all were very informative and helped me shape a better presentation. Although i received lots of emails saying that installation under Linux / Unix is easy .... still emails asking for help in installing R itself, or external packages and such crop more often than not on the list and for this reason i pressumed it is harder to install under Linux

I am the maintainer of its, but not it's original author. One of the main strengths of its is that it uses POSIXct dates. Zoo has the flexibility of using almost any date format, but I don't know if the other date formats can store hour, min, sec data. You might want to do a little exploring with each before you commit. I'll be happy to give you a hand if you decide to work with

My objective is to start having meta-data on objects that I create. For example, consider the following function: assign2 <- function(x, ...) { assign("x", ...) attr(x, "creation time") <- Sys.time() x <<- x } assign2("x", 1:4) "assign2" assigns to x the vector 1:4, and it then also adds the creation time of the object. (Hat tip goes to

I was thinking about running Wine on Interix (the POSIX layer of Microsoft's Services for Unix). There are a few apparent unknows: Would Wine load the .dll.so's? Since Interix uses PE for it's native format (running on Windows, duh), Would Wine load the .dll.so's? Would it reject them being in PE format and having the 'POSIX Layer' attribute set, or could we hack on a

Relative newbie so would welcome comments re structure of a self-referential relationship I''ve got. It''s started off similar to the Person HABTM friends in the Rails recipes books (working fine), but I needed to turn the join table into a full-blown model as I wanted to add attributes to it. Few tricky bits dealing with the new :through structure and understanding how :scope

I've read that certain operations performed on a matrix (e.g. ribind, cbind) are often much faster compared to operations performed on a data frame. Other then the "bind functions", what are the main operations that are significantly faster on a a matrix? I know that data frames allow for columnnames and rownames, and that each column in a data frame can have different data types.

Can anyone comment or point me to a discussion of the pros and cons of robust regressions, vs. a more "manual" approach to trimming outliers and/or "normalizing" data used in regression analysis?

I have Samba running without a PDC and I have some questions about the advantages for implementing one with Samba vs. the problems and disadvantages. Perhaps some kind souls can help me determine whether I should do this or not. We have three offices connected by a Checkpoint VPN, plus people "on the road" using their SecureClient tool. We want everyone to be able to get to all the

In a previous thread, Tom listed advantages (reproduced below) of Proxy ARP over NAT. They are great reasons, but I have one reservation. By using private addresses with NAT for servers in my DMZ, I can granularly allow specific traffic, such as to/from the SMTP gateway/relay in the DMZ, to connect inbound from the DMZ to an internal (LOC) mail server, and know that it comes only from a

Hello Boys and Girls and Everybody. I have recently started using a Macintosh computer to replace the dinosaur of an unbelievably unreliable PC that I have been using for the last 10 years. So far I have been very pleased. I have been using OpenOffice for quite a while now as I find it is mostly superior to Microsoft Office in many ways, HOWEVER - OpenOffice lacks the Voice Recognition Software

Hi, I am doing a very informal presentation for my office about R capabilities to deal with and analyze spatial data, display data and maps, and connections with GIS. I've used in my presentation info from the CRAN, the spatial Task view, and the more striking graphics examples from http://addictedtor.free.fr/graphiques/thumbs.php and NCEAS

2009/3/7 Rosanne DiMesio <dimesio at earthlink.net>: > I can think of one possible benefit. There are a lot of apps without maintainers, and there might be users of those apps who would be willing take a few minutes to post bits of useful information in a wiki, but don't want the responsibility of being a maintainer. Sure, they could just post info in a comment, but user comments are

Before adding a second interface to my asterisk box I'd like to get some feedback on having and internal interface with a private address and external interface with a public interface. You know like pros, cons, configuration suggestions, and anyone's true experience trying such a design. I have one concern. Is asterisk aware enough to respond to traffic with the correct ip address? In

Hi, I'd like to propose that we introduce a mechanism in LLVM for declaring that the symbol for a given global variable should be assembled at a given offset from the start of the data for that global. The main reason for doing this would be to allow a module to conform to an externally imposed ABI which requires data to be present below a symbol. We have two specific use cases in mind at

I know this thread has been discussed before, but I have run into this problem and would like to re-open it... I have come to a point in my project where I need to provide an import/export feature for Active Records. Since a user could export off one system and import onto another auto-increment integers will not work (collisions on ids due to lack of uniquness). Listed below is an initial list

OK we talked about this a while ago, here's a summary and some proposals: At the moment, virtio PCI uses IO BARs for all accesses. The reason for IO use is the cost of different VM exit types of transactions and their emulation on KVM on x86 (it would be trivial to use memory BARs on non x86 platforms if they don't have PIO). Example benchmark (cycles per transaction): (io access) outw
