Dear alls, Could someone tell me how to select a subset of string observations (e.g. "females" in a sex column) with sqlQuery in the RODBC library? Indeed, I'm trying to select a subset of observations on my access database with: female<-sqlQuery(mychannel,"SELECT Micromammiferes.sex FROM Micromammiferes WHERE (((Micromammiferes.sex)="females"));") The sql

Hello all, I have a vector of character strings, in which I have letters, numbers, and symbols. What I wish to do is obtain a vector of the same length with just the numbers. A quick example - extract of the original vector : "lema, rb 2%" "rb 2%" "rb 3%" "rb 4%" "rb 3%" "rb 2%,mineuse" "rb" "rb" "rb 12"

I'm trying to boot linux on a VIA EPIA-M board (a Nehemiah-based M10000), and I'm having some trouble with it. I'm watching the network transactions with ethereal, and I'm seeing a failure at what appears to be the tftp stage. The M10000 picks up its IP address from the dhcp server (ISC DHCP3), and reports it correctly on the screen. Then the tftp session starts, and I get the

First issue is that unittests don't build for MingW, the attached patch should fix it. Second issue is that llvm-gcc fails for me with the following error: /c/cygwin/home/jlerouge/buildbot/llvm-test/gcc-build/./gcc/xgcc

Dear all, I'm building binomial mixed-model using lme4 package. I'm able to obtain outputs properly except when I include two particular variables: date (from 23 to 34; 1 being to first sampling day) and Latitude (UTM/100 000, from 55.42 to 56.53). No "NA" is any of those variables. In those cases, I get the warning message: "nlminb failed to converge" I tried to

Hello, Rather new to RoR, so I''m not sure about the terminology and such :-/ . My question is: how could I know the model which is associated to a controller?

Hello, I always have the same kind of design problem, which I am not sure how to solve correctly: - say I have a variable, "status", which I want to calculate once in my controller, and access a couple of times in my view - "status" variable initialization could happen in a subclass, overriding the regular method for that What I do now is using an instance variable

Dear all, I'm doing univariate Poisson regressions using the "glm" and "glm.fit" functions. I have 5 independent datasets and each dataset, has one response variable and more than 20 factors to test. Currently, I run one regression at a time and manually take notes of the results in excel to have a quick overview on what is going on in my data. My poor method is very

One more question: Is there some way to set the human_name of a column? e.g.: human_name for column address1 shouldn''t be Address1 but "Address, line 1".

Hello alls, I found in the literature a technique that has been evaluated as one of the more robust to assess statistically the significance of the loadings in a PCA: bootstrapping the eigenvector (Jackson, Ecology 1993, 74: 2204-2214; Peres-Neto and al. 2003. Ecology 84:2347-2363). However, I'm not able to transform by myself the following steps into a R program, yet? Can someone could help

Dear all, I get an error message when I run my model and I am not sure what to do about it. I try to determine what factors influence the survival of voles. I use a mixed-model because I have several voles per site (varying from 2 to 19 voles). Here is the model: ### fm5 <-lmer(data=cdrgsaou2, alive~factor(pacut)+factor(agecamp)+factor(sex)+ResCondCorp+(1|factor(cdrgsa ou2$ids)),

Hello, I have a People table and a Addresses table. A person can have one or more addresses, but should at least have one, so there is a address_id field in People. Now, I would like to have a form to fill the name of a new person and its address from the same place. I could use person.address.country, for example (it works), but I would like to simply use person.country for some reasons
