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)})
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

See if this does what you are expecting.
xYplot(Cbind(b, b-1.5, b+1.5)~a, ylim=c(0,max(b)+3),
panel=function(x,y,...){
panel.xYplot(x,y,subscripts=x,...)
panel.superpose(x,y, subscripts=x, groups=x,...)
ltext(x=list(1,2,3,4),
y=list(13,14,15,16),
labels=list("A","B","C","D"), pos=2)})
