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
