Hello,
 
I am fairly new to R and having a problem with the lme command. I have searched on forums, read the Fox 2002 chapter, and R help, but the suggestions that I have tried have not helped me.
 
My data file is called Acsdata. 
 
This is my script:
 
Acsdata.1 <- lme(Acsdata$gsi ~ Acsdata$asitotal + Acsdata$famstrto + as.factor(Acsdata$GEN) + Acsdata$asxfs + Acsdata$asxpar + Acsdata$asxgp + Acsdata$asxfsxpa + Acsdata$asxfsxgp, random = ~1|Acsdata$family)

I keep getting the error: object "gsi" not found. However, when I use the summary function, R is able to recognize gsi.
 
I welcome any suggestions.
 
Thanks
