nlminb failed to converge with lmer
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

Help on estimated variance in lme4
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)),

sqlQuery of variable of type varchar - confusion with "."
Dear list, I have a rather large dataset in SAS which I export to a SQLite database for subsequent use in R. One of the columns is cowidp 1881501224.2 1881501224.2 and the column is stored as a character in SAS. It becomes a varchar in the database (it should be - it is an identifier; not a number). Reading this into R gives cowidp 1 1881501224 2 1881501224 .... - i.e. the

RODBC sqlQuery insert slow
Large for loops are slow. Try to avoid them using apply, sapply, etc. I've made the paste statements a lot shorter by using collapse. See ?paste for more info.
