Can a single random number be generated in R? I have an exercise that wants to simulate coin tosses, and I cannot seem to find a good example of the use of random number generation in R. Any help? Joshua Gramlich Chicago, IL

Hello, My questions are meant to be not necessarily specific...I am looking for advice and best practices for setting up an R environment. Here's my situation: I am one of perhaps three or four individuals who will be analyzing the same data through the use of R. I would like to set up a "base" environment for our project, basically some scripts that connect to a database, load

Is there a way to edit user defined functions once they've been created? For instance, I've a simple function that plots a table, but I'd like to go back and add more parameters to the barplot call. Is there a way to change this function without completely starting from scratch? Other than storing the code in a file and re-running it? Joshua Gramlich Piocon Technologies Chicago,

I don't suppose it's possible to create a pie chart in R? I've got 1500 some odd elements in a frame that are valued at either -1, 0 or 1 and I'd like to find a reasonable way to represent the distribution graphically...any ideas? Joshua Gramlich Piocon Technologies Chicago, IL

Is anyone using R with postgres? I'd like to do so, but cannot seem to find any reasonable explanation of how to do so. Joshua Gramlich Chicago, IL

Greetings humans, first post alert. I've used the search to no avail...I'm running Ubuntu 9.04 on an AMD64. I have Wine version 1.1.22, and it seems to have installed ok. I can run winecfg no problem, and also notepad from the applications menu, which is really the only test I know how to do. I've got a piece of software called PL/SQL Developer, which is in the apps db and looks

Hello ... Does anyone know of a package (or other code) out there which has handled S4 classes in C? I realize that a lot of this stuff is fairly new in R-devel, so my assumption is no - but there seems to be some deviation from the green book that is really throwing me off, and I'm looking for some sort of front-to-back example. Thanks -Jeff

When I run rake test:units I get this error: 292 tests, 350 assertions, 2 failures, 13 errors rake aborted! Command failed with status (1): [/usr/local/bin/ruby -I"lib:test" "/ usr/loc...] This error just showed up yesterday --- I have no idea how I caused it. Here is my gem list in case that helps: actionmailer (2.3.2, 2.2.2) actionpack (2.3.2, 2.2.2) activerecord (2.3.2, 2.2.2)

Hello, I''m experimenting with VGA pass-through using debian wheezy with the debian 3.2 kernel. I could get pass-through of my onboard intel card without much problems, but I didn''t have any luck so far with my nvidia gtx 580. I have two general questions regarding this: 1) What is the best Xen version to try this? I tried 4.2, but could only find patches for a quite old

One quirk to be watched is the use of connections to the DBMS via the Unix sockets vs ports. The PostgreSQL driver bundled with unixODBC will use Unix sockets to `localhost', but this driver seems unreliable (see the ChangeLog). The current driver will only use a TCP/IP port, and to use that needs postmaster started with the -i flag (which is not the default) and with tcp/ip

There was an inquiry on this list recently about plotting some simple error bars on a graph. Now Splus has a function (error.bar --- originally written by Sue Clancy of DMS, CSIRO, I believe) to do this job virtually at the touch of a key. (Well a few keys. :-) ) The error.bar function is written completely in raw S --- no calls to ``.Internal'' or anything like that. So it would be

Hello together, i want to run LCDHype in Linux under wine, because there is no adequate other program that supports graphically LCD-Displays. I already opened a discussion in the forum of LCDHype (sorry - is in german language): http://lcdhype.condense.de/index.php?showtopic=4963 I already found an older version (V 0.6) of LCDHype that installs and the frontend is up and running. But now i am

I''ve been working with Gruff to do all my apps graphing and such etc. I love it but I''m just having a hard time customizing the graphs, but this is perhaps due to my inability to comprehend the online RDocs. What I want to do is adjust the width / heights of my graphs or at the VERY LEAST the heights. It seems that if you scale a graph anywhere below 400-450px it is pretty

Unfortunately a number of our clients need extensive reporting capabilities. There are a number of Java 3d graphing libraries like the link below and PHP offerings out there. http://big.faceless.org/products/graph/index.jsp .Net has its new report viewer control for ASP.net 2.0 which allows you to create 2d/3d reports containing pie charts, line graphs etc. Whats cool about this control is

I''ve searched far and wide for a decent graphing solution that i can use easily with ruby. It needed to be fairly advanced (not Gruff),simple, powerfull. It''s called ploticus http://ploticus.sourceforge.net/doc/welcome.html There is a ruby wrapper for it but the site is currently down, so i''m using it via CGI on my Apache server. It''s great. Just thought

Hello everyone, I''m looking to produce some graphs broadly like the ones shown here: http://www.dotnetcharting.com/gallery/List.aspx?gal=6 No prize for guessing what type of app it is... This particular graphing library is .NET-specific, but as you can see the results it produces are really nice. More than likely, they''re several notches above what I''ll be able to

Hi all, This might be OT. Wondering what are available charting solutions that work well with Ruby on Rails. I''ve seen reference to a few but they all seem to rely on integration with a program written in another language (requiring a seperate process per chart), Perl''s GD module for instance. Is there a 100% Ruby charting library that is freely available? Thanks, Dave
