similar to: Cloud demographics

Dear All: I have a clinical study where I would like to compare the demographic information for 2 samples in a study. The demographics include both categorical and continuous variables. I would like to be able to say whether the demographics are significantly different or not. The majority of papers that I have read use multiple techniques to achieve this (e.g., t-test for the continuous

Hi all, I got curious about something, so in proper scientific fashion I obtained some data and analyzed it. Question: what is the female participation in the R-help email list? Data: the most recent list postings, obtained from the website. I took my best shot at classifying the names given in the email header as male/female, but ended with a fair number of unknowns. This dataset had 2797

Hi all, is there a known issue with health monitoring on supermicro SuperServer 6010H? (Im primarily interested in temeperature monitoring) I have tried both mbmon and lmmon with the following results: stats# mbmon -d SMBus[ServerWorks(ServerSet Chipset)] found, but No HWM available on it!! No Hardware Monitor found!! InitMBInfo: Unknown error: 0 stats# lmmon IOCTL: Operation not supported by

Hi! Attached patch makes xen-tools and stubdom-dm going independent from hardcoded pathes. It is no possible to install into /usr/local or any other non-default directory and use it out-of-the box. This allows us to have different Xen versions in different directories, simplifies packaging for distributions. It also finds ''hvmloader'' and

The current development version dies in qbeta() when compiled with egcs -O, egcs 1.0.2 and glibc 2.0.7 (RedHat versions). Since this also kill the F and t distributions, it doesn't exactly do wonders for R's usefulness... Anyone else seeing this or has my setup just gone out of whack? It does look pretty much like a clear compiler bug when inlining math functions (storing temporaries

Hi Folks, Troll trumps your existing ActiveResource mocking libraries like inbuilt HttpMock,Fakeweb or Webmock out of water. With Troll, ActiveResource mocking just works, some of its features: 1. Don''t need to mock calls at Net::HTTP level (which webmock,fakeweb do). Really, we don''t care what HTTP library ActiveResource uses, fakeweb and webmock bring additional complexity

Dear R users, I am trying to convert a dataset from one format to several rectangular datasets. A consultant helped design the data entry program for our survey using Delphi/Pascal and for each household the information is stored in a file called "EA-HM-HH.TXT" where EA is the enumeration area number, HM is the homestead number and HH is the household number. Within this file the

Avi , Your question is not dumb. Let me ask a more fundamental question. What is R tools, what does it do, and how is it used. From time to time, I receive a message when I down load a package saying I need R tools. When I receive the message, I don?t know what I should do, other than down load R tools.

Hello All, Need to coalesce some columns using R. Looked online to see how this is done. One approach appears to be to use ifelse. Also uncovered a coalesce function in the BBmisc, emoa, and microbenchmark packages. Trouble is I can't seem to get it to work in any of these packages. Or perhaps I misunderstand what it's intended to do. The documentation is generally pretty scant. Working

I have also had difficulty running R in RStudio. Has anyone else had problems? It will be a shame if we need to abandon R Studio. It is a very good IDE.

Hi everyone, my apologies in advance if I'm overlooking something simple in this question. I am trying to use R's survey package to make a direct method age-adjustment to some complex survey data. I have played with postStratify, calibrate, rake, and simply multiplying the base weights by the correct proportions - nothing seems to hit the published numbers on the nose. I am trying to

I am working on an app with a requirement that has yielded an unexpected problem for Rails routing. We have several controllers that handle regional data (one controller per data type - weather, demographics, etc). The problem is that there is one region who''s actions and output are different. We intend to create two controllers for each data type (i.e. weather_controller to handle

TaxAct 2006 installed perfectly, and at the end of the install I was given the option to start the program. I said yes, and the program ran just fine. However, when I tried to run the program separately, I got this error: root@PC1:~/.wine/drive_c/Program Files/2nd Story Software/TaxACT 2006# ./TaxAct06.exe run-detectors: unable to find an interpreter for ./TaxAct06.exe Any idea how I can help

David, I greatly appreciate the explanation you gave regarding R tools providing tools available in Linux distros, but not found in Windows. (I am using a windows system). Does this mean that Linux users don't need to use R tools when they want to compile R code? Additionally, thank you for the information about what I should read. I will look at the material again, and hopefully things the

Hi all, I'm using RODBC library to connect to a database.

Hi Hugo, I've been able to replicate your bug, including for other distributions (runif, rexp, rgamma, etc) which shouldn't be surprising since they're probably all drawing from the same pseudo-random number generator. ?Interestingly, it does not seem to depend on the choice of seed, I am not sure why that is the case. I'll point out first of all that the R-devel mailing list is
