Hi, After playing while with ActiveRecord, I''m surprised it isn''t easier to insert data into a table whose primary key is not auto-incremented by the database server. The following code... --------------------------------------- -- MySQL database "test" --------------------------------------- CREATE TABLE gardens ( code integer NOT NULL, name

Hi, I''m using drbfire to send a "DRbUndumped" ActiveRecord object from the server to the client, through an ADSL line of 4Mbits/s download, and 600Kbits/s upload. I was afraid there would be too many round-trips between the client and the server, and unfortunately this is true: Server code: ------------ #!/usr/local/bin/ruby require ''rubygems'' require

Hi all, I''m trying to get text on to the screen in response to pressing a button. This code doesn''t work, and I don''t know why. My puts command says that the window is shown, but it''s not displayed. Also, it seems to me that there should be an easier way to get text on a screen in response to pressing a button. Any hints? Thanks! Marlene require

Hi, I am running glm logit regressions with R and I would like to test a linear combination of coefficients (H0: beta1=beta2 against H1: beta1<>beta2). Is there a package for such a test or how can I perform it otherwise (perhaps with logLik() ???)? Additionally I was wondering if there was no routine to calculate pseudo R2s for logit regressions. Currently I am calculating the pseudo R2

Please do give reproducible example. The code you gave, which you claimed `works correctly' doesn't: > SDT.Optim <- function(crit = NULL, Hess = F) + { + q <- length(par); x <- data + if(hasArg(crit)) + cat("\n Crit present\n") + else +

Dear R Users, Here is another probelm/question. I would like to run some panel regressions with R. Therefore I have combined several time periods of data for different individuals in my database. I have already run pooled OLS but I would need to calculate a Fixed Effects Estimator (within estimator). Unfortunately I couldn't find anything like that in the RSearch and I suppose that lme

Hi, I''m using FXRuby 1.6.13 under Windows XP / Ruby 1.8.6. I''ve noticed something strange when copying-pasting things between FXTable cells, and FXTextfields. ---------------------------------------------- 1) When copying the content of an FXTextfield, and pasting it into an FXTable cell, everything works fine. 2) When selecting an FXTable cell, issuing a "copy"

Dear list members, I have a question concerning multiple comparisons after using glm. My response variable is days until emergence of an insect species. The explanatory variables are sex (two levels), parasitoids added (two levels) and populations (34 levels). I would like to know now which populations are different in days until insect emergence. For this I used multiple comparisons as

I wanted to use the nls() module to solve a Problem from Sen & Srivastava (1990, p.209). Here is the (basic) code used to perform the estimation: library(SenSrivastava) library(nls) data(E9.8) # Use Linear Least Square for estimating start values lm.obj <- lm(R.1 ~ I.1 + S.1, data = E9.8) nls1.obj <- nls(R.1 ~ b.0 + b.1*(I.1^a.1-1)/a.1 + b.2*(S.1^a.2-1)/a.2,

Dear ladies and gentlemen, I have recently installed the latest version of R (4.3.3) for windows. Now I have the following problems with mutated vowels like ?, ?, etc. Here is an example: If I type the command: Dir <- "C/Users/macho/Documents/_LVn/Experimentelle ?bungen" in the R console there is no problem. However, if I put the same command into a source file (e.g. Test.r) and call

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

Dear all, I am using the hclust method in R. I am building nice dendrograms with it. Actually for my further analysis I want to get the number of bifurcations (bif) for each object (labels) in the dendrogram. That has to be calculated by the colums merge, height and order. http://www.nabble.com/file/p16142989/Sc2Mown_Pred.txt Sc2Mown_Pred.txt Sc2Mpred<-

Hello, I'm currently dealing with a rather strange problem when using the function "stepAIC" ("MASS" package). The setting is the following: From model learning data sets ("learndata"), I want to be able to build prediction functions (in order to save them in a file for further use). This is done by the function "pred.function" (see below). Therein,

The new code is dedicated to calculate free inodes number of all inode_allocs, then return the info to userpace in terms of an array. Specially, flag 'OCFS2_INFO_FL_NON_COHERENT', manipulated by '--cluster-coherent' from userspace, is now going to be involved. setting the flag on means no cluster coherency considered, usually, userspace tools choose none-coherency strategy by

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it?

Hi, A quick question from a beginner: does it make sense to build the UI of a rails application with Qt, instead of bulding a web application? The idea would be to reuse parts of rails (like ActiveRecords) to write the logic on the server, and build the (complex) UI faster, with a client-based framework. On the client, ruby *could* be used too, since QtRuby exists. Your reactions are more than
