[R] MuMIn package: plotting averaged model estimates with CI

2013-07-03 Thread Katarzyna Kulma
Hiya, I'm fairly new to MuMIn (and plotting predicted values in R, for that matter) and I have quite a basic question: I want to plot model-averaged estimates with their 95% CI's for the supported interaction (Infection x ecs). I used the following data: > head(summ12b) ld sum12 Infection

[R] Fwd: binomial glm and sole effect of the treatment

2013-05-10 Thread Katarzyna Kulma
Hiya, I'm using simple glm binomial models to test the effect of treatment (factor, 3 levels) on infection prevalence (infected/uninfected): ad3<-glm(Infection~ecs, family=binomial, data=eilb) but summary() function returns for each of the factor-level coefficients against the control treatment:

[R] R does not subset

Hi everyone, I know there have been several requests regarding subsetting before, but none of them really helps with my problem: I'm trying to subset only infected individuals from the REC2 data.frame: > str(REC2) 'data.frame':362 obs. of 7 variables: $ RINGNO : Factor w/ 370 levels "BL1

[R] dredge solely offset models in MuMIn

2012-07-27 Thread Katarzyna Kulma
a table with offset models only? Not sure if I define something incorrectly or maybe there's a different way to get around that? Will appreciate any suggestions cheers, Kasia Katarzyna Kulma PhD Student Department of Ecology and Genetics Institute of Ecology and Evolution/Animal Ecology
