Changing an unordered factor into an ordered factor
I'm trying to change an unordered factor into an ordered factor:
data96$RV961327 <- data96$V961327
data96$RV961327[data96$V961327 %in% levels(data96$V961327)[4]] <- NA
data96$RV961327[data96$V961327 %in% levels(data96$V961327)[5]] <- NA
data96$RV961327 <- factor(data96$RV961327)
attributes(data96$RV961327)
levels(data96$RV961327)

Running a Logit Model in R
...an R newbie and had the following question. I'm trying to run a logit model because I have a dependant variable that is a factor with three levels. Each of my independent variables are factor variables and have two or more levels, which is why I'm unsure about the error.
regone <- glm(data96$RV961327 ~ data96$RV960605 + data96$RV960610 + data96$RV960337 + data96$RV960385 + data96$RV960417 + data96$RV960615 + data96$RV960698 + data96 $RV960714 + data96$RV961145 + data96$RV960067 + data96$RV960702, family=binomial(logit))
This produces the following error.

Recoding Variables in R
...public opinion question from the ANES. I would like to throw out 8 and 9. Furthermore, I would like to reorder the responses so that:
1. Oppose (originally 5)
2. Haven't though much about this (originally 0)
3. favor (originally 1)
I tried the following, which did not work:
library(car)
data96$V961327 <- recode(data96$V961327, "c(1)=2; c(2)=3; c(3)=1")
I also tried the following, which also did not work:
new <- as.numeric(data96$V961327)
new
data96$V961327 <- recode(new, "c(5)=1; c(0)=2; c(1)=3")
Help,

How to tell R to start reading from 1 to 365 in order.
