Objet : [R] Regarding lme functions

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

Subject: [R] Labeling points with xYplot
To: r-help@r-project.org
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)})
