Hi all,

I recently got accquainted with the R stats and using the 'lme' function for some of my analyses. Since I am a novice, I am facing a lot of problems regarding the analyses.

I have applied the Linear Mixed Effect model for my dataset and would like to know the commands for extracting the confidence interval for the fixed effect.

Also would like to request if you can kindly guide me the command for plotting the observed value vs the value predicted from the mixed effect model.

Thanking you

Regards

Ratna

Date: Monday, 10 November, 2008, 9:56 PM

Hello R-Users,

I am trying to label points on an xYplot. I can label the points, but then I lose the error bars. I suspect that I should be using panel.xYplot rather than panel.xyplot, but that didn't work either...

Can anybody help me out? Example code is below. First xYplot has error bars, second tries to label the points and the bars disappear.

Thanks,
John

a=c(1:4)
b=rnorm(4,15,5)
blab=b+1

xYplot(Cbind(b, b-1.5, b+1.5)~a,

ylim=c(0,max(b)+3))

```xYplot(Cbind(b, b-1.5, b+1.5)~a, ylim=c(0,max(b)+3),
panel=function(x,y,...){
panel.xyplot(x,y,...)
ltext(x=list(1,2,3,4),
y=list(13,14,15,16),

```

labels=list("A","B","C","D"), pos=2)})
