Hi, I went for a slight alteration of your solution x1<-c(1,2,3,4,NA ,NA ,NA, 3, 1, 1, 1, 1, 2, 2, 3, 4, 4) x2<-c(2,3,4,3,4,3,4,2,2,3,4,NA,NA,NA,NA,4,3) x3<-c(1,1,1,1,"aaa",2,2,2,3,3,3,3,4,4,4,1,2) m<-data.frame(x1,x2,x3) m<-replace(m,is.na(m),"NA") levels=unique(as.vector(as.matrix(m))) mapply(f

[R] Error message in lmer

Dear list I try to run a bootstrap with lmer. I often, but not always, get the error message: Error in objective(.par, ...) : Leading minor of order 6 in downdated X'X is not positive definite (with the number (here 6) varying) In R-archives I came across some threads that treated this pro

[R] panel data analysis possible with mle2 (bbmle)?

Dear R community, I want to estimate coefficients in a (non-linear) system of equations using 'mle2' from the "bbmle" package. Right now the whole data is read in as just one long time series, when it's actually 9 cross sections with 30 observations each. I would like to be able to test and correc

Steve, - Use tranparancy to prevent overplotting: more details on p. 16 of the ggplot2 book: http://had.co.nz/ggplot2/book/ - You can choose your own colour with scale_manual(): http://had.co.nz/ggplot2/scale_manual.html - The backgroundcolor can be set with ggopt(background.color = "white"): htt

Hi Here is an alternative solution which will include count of the NA. It may not be "formally" correct, but it seems to work: > mapply(function(x) table(factor(ifelse(is.na(x), "NA", x), levels=c("NA",1,2,3,4))), m) x1 x2 x3 NA 3 4 0 1 5 0 5 2 3 3 5 3 3 5 4 4 3 5 3 > H

Re: [R] Mixed effects model with binomial errors - problem

First of all I'm forwarding this mail to the R-SIG-mixed-models, which is more appropriate to your question. Remember that family = bionomial uses by default the logit link. Hence all parameters will be on the logit scale. So you will need to backtransform them for comparison. Then you'll see tha
