For starters, let me say again how impressive R is, and how all of the effort that has gone into R shines through clearly. It is an amazing program, and I am frequently pleasantly surprised to find out how powerful and capable R is. Finding the interface to xgobi is the latest pleasant surprise. Are there functions in R for Major Axis and Reduced Major Axis regression? I have OBS-RESID graphs of

Hi there, This problem has been dogging me for a bit, and I'm trying to figure out why. When running the the subsets function in the leaps library, R is giving me the following error message > lvodsub <- subsets(pred, resp$LVOD) Warning message: XHAUST returned error code -999 in: leaps.exhaustive(a, really.big = really.big) but this still happens if I add the really.big option:

Hi- I'm trying to read data into R that was exported from Excel, as tab-delimited text. There are some empty cells in the spreadsheet, which I'd like to treat as missing values. I'd like to specify to read.table to use a *single* tab character as the record separator, but I can't seem to do this. First of all, how can I get a tab character in R? Second, is it possible to force

Is there a simple way to run cor.test on for a matrix of correlations? Of course, cor on a data frame produces a correlation matrix, but cor.test will only take two variables at a time. Is there a way to get behavior similar to that of cor with cor.test? I suppose the programming alternative would be to run two for loops with the number of items and cor test embedded accessing the columns of

Hi guys.. I have a very strange problem with Samba version 2.0.5a and Q&A Ver 5.0 for DOS (eeek.. I know.. Symantec stopped supporting it 2 yrs ago) The error i get is: ! Problem ! System error, please try again (see Appendix C). Press Esc to cancel. Ref#:04EC It seems to be related to drive size/samba/fstype or something.. The share that I am mapping the clients to (win95 and win 311)

Hi there, I realize that this is a bit of a strange question, but here goes. In SAS, one can use the REG procedure to carry out a least-squares regression analysis. By specifying the R-SQUARE option in the SELECTION command, the program carries out regressions for every combination of every independant variable against the dependant variable. This is useful in smaller datasets, though difficult

There is a new initiative to open a community based Q&A website which is based on the StackOverFlow engine - to answer data-analysis (and obviously R) related Questions. After good several months of using StackOverFlow (see the R tagged questions here <http://stackoverflow.com/questions/tagged/R>), I came to the conclusion that it offers a very good web 2.0 solution for collaborative

Hello, I''ve published a Q&A in the Vancouver.rb series with Brock Whitten. Questions include: * How did you get started with Ruby on Rails? What makes Ruby on Rails a great choice for developing web applications/sites? * Can you tell us some challenges you''ve faced developing using Ruby on Rails? * Off the Rails - Can you tell us a little bit about Merb?

Hi guys, I'm a long time user of a site called Stackoverflow, which is a specialised question and answer site for programming. (Think Experts Exchange, but free.) Anyway, I decided today that it might be useful to have an equivalent for web radio. So I put in a proposal to the Stackoverflow guys. Now I just need people to express an interest in it, so that the Stackoverflow people will

The following question was posed by Simon Easter on the XenProject.org Q&A area. Please reply to me so I can post your answers to the site or, if you feel so inclined, answer yourself on the website: I have a need to run very low weight PV debian guests under a kvm hypervised guest .(i.e. split a vm using pv - the reasons are varied but essentially each host has to have it''s own

Whilst bored I purchased HalfLife for Windows, having read people mention on Slashdot that it runs on Wine. I run Debian (woody) on an AMD Athlon 1.4GHz machine with 1Gb RAM as my desktop. It currently has a Voodoo3 video card, though I have a dual head Radeon which I'm going to use once I get a monitor that is compatible (my current monitor has a very wavy display with that card). I

Dear r-help, Could you help me to find a solution for this error: Il y a eu 50 avis ou plus (utilisez warnings() pour voir les 50 premiers) > warnings() Messages d'avis : 1: In if ((data[pa, k] == df[, j]) & (data[ch, k] == i)) { ... : la condition a une longueur > 1 et seul le premier élément est utilisé 2: In if ((data[pa, k] == df[, j]) & (data[ch, k] == i)) { ... : la

Hi gang, I'm perplexed- I have some code that uses for() loops that works fine in R version 2.8 on my mac, worked fine in version 2.8 on my old windows machine, but doesn't work in version 2.10 on windows. The loop implements a function over a data frame (code is included below). In Mac (running version 2.8), the results of the loop are what I expect: > p_unadj [1] 0.034939481

I am trying to run the following model in R > lmer(leaves.eaten~Geocytotype+(1|TEST/ PLANT),data=cyphoplantfeeding,family=poisson) My experimental setup is 41 replicates (TEST) of an experiment in which there are three Geocytotypes of a plant species in each TEST, and two plant pseudoreplicates per Geocytotype in each test (i.e. 3*2=6 plants per test). So my random factors are trying

This is not a new bug as I found the behaviour on many version of rsync . When you use the --delete option combined with --backup, the expected behaviour is to backup the deleted file on target machine by renaming it with the backup suffix or with ~ suffix by default. This works fine but when you execute the same command a second time, like my cron job does the next day, the backup file gets

The delete-dir-and-suffix patch creates two new command line options as follows: --delete-dir --delete-suffix The delete-dir and delete-suffix options give the ability to store backup of deleted files on the receiver in different directories or with different suffix than the backup of files that have been changed but that are still on the source drive. Both commands can be

I have two issues. 1-I am trying to use morphology to identify gender. I have 9 variables, both continuous and categorical. I was using two-step cluster analysis in SPSS because two-step could deal with different types of variables. But the output tells me that an animal is in cluster 1 or 2, it does not give me a probability (ex. 0.70 cluster 2). I also did not want to specify that I want two

I have to admit that I'm at a bit of a loss here; any pointers would be greatly appreciated. I've been making correlation matricies from some of my datasets, and have been instructed to get the probability values for each of these correlations. I've checked the online help for info on both the cor and cov functions, but I was unable to find any relevant info on finding how to obtain
