just a guess but does it know where to look for the variable? has the data
been specified? i am not seeing any of the previous messages in this thread so
forgive me if this has been mentioned.
that error means it has no idea where to find the dependent variable 'Pat2006'.

if that is not specific (or not general) enough:
newDV <- dat$DV ## newDV is my DV & it is continuous.
newDV <- as.numeric(newDV)-5
str(newDV)
(i had to do a great deal of coding here so i am snipping down to the end)
tmp[which(dat$v1 == "stuff" & dat$v2 == "more stuff")] <- "lots of stuff"
hello. help with effects plots. here's the last bit of code before running
the model and then the effects, then the error.

str(nor.dem)

I have a dataset which I am calling RB09.
I am trying to match the questions in the code book with variable codes.
It is not very intuitive.

Hello, all.
I have come across a problem. Previously, when I recoded my DV, added the
variable to my dataset and ran the multinom, I was just fine. But I am doing
it again and I am getting this error.

Error in `$<-.data.frame`(`*tmp*`, "trust", value = c(NA, NA, NA, N
I see the problem. So Sorry.

hello,
i need to recode a variable, however the contraction is causing problems. i
had the code to change this written down somewhere and i just can't find it, of
course.
i am using the car library to recode.
it's only 5 levels when it should have 6... when i do levels(trust).

Sounds like you are hypotesis testing. you can try "an R companion to applied
regression" 2nd edition 2011 by john fox and sanford weisberg.
effects package does interactions quite well.
