Plotting Confidence Intervals
Hi Andre,
Perhaps you want something like this:
plot(c(p_conf[1],p_conf1[1],p_pred2[1],p_pred3[1]),xaxt="n",
xlab="Model",ylab="Estimate")
axis(1,at=1:4,labels=c("p_conf","p_conf1","p_pred2","p_pred3"))
library(plotrix)
dispersion(1:4,c(p_conf[1],p_conf1[1],p_pred2[1],p_pred3[1]),
ulim=c(p_conf[3],p_conf1[3],p_pred2[3],p_pred3[3]),
llim=c(p_conf[2],p_conf1[2],p_pred2[2],p_pred3[2]),interval=FALSE)

Hi Kehl, First i would like to thank you for the support. to respond your question i want rather the 4 intervals with the labels, but another one with the 4 bars with the intervals, it was fantastic! Thank you again! 2015-05-02 9:24 GMT+01:00 Kehl D?niel <kehld at ktk.pte.hu>:
Hi Andre, I think you'll have to give some more information about what you want to see on your plot. The 4 intervals with labels? A bar with an interval maybe? Four bars with the intervals? Only two showing differences between conf and pred intervals? Also you do miss a 1 here I guess: p_conf1<- predict(ines,interval="confidence",NJ,level=0.99) p_conf1 #Intervalo de confian?a para o estado NJ e para um nivel de 99% round(p_conf, digits=3) last line should read p_conf1 here? Best, d

Hi Guys,
It's the first time i use R-Help and i hope you can help me.
How can i plot conffidence intervals? with the data bellow:
#Package Austria
library(car)
#head(States)
States1=data.frame(States)
ines=lm(SATM ~ log2(pop) + SATV , data=States1)
summary(ines)
NJ=as.data.frame(States["NJ",c(4,2,3)]) #Identifica??o do estado NJ
p_conf<- predict(ines,interval="confidence",NJ,level=0.95)
p_conf #Intervalo de confian?a para o estado NJ e para um nivel de 95%
round(p_conf, digits=3)
p_conf1<- predict(ines,interval="confidence",NJ,level=0.99)
p_conf1 #Intervalo de confian?a para o estado NJ e para um nivel de 99%
round(p_conf, digits=3)
p_pred2<- predict(ines,interval="prediction",NJ,level=0.95)
p_pred2 #Intervalo de perdi??o para o estado NJ e para um nivel de 95%
round(p_pred2,digits=3)
p_pred3<- predict(ines,interval="prediction",NJ,level=0.99)
p_pred3 #Intervalo de perdi??o para o estado NJ e para um nivel de 99%
round(p_pred3,digits=3)
Thanks
