Dear all,
When I try to run IDEAL it gives me an error saying: Error in
ideal(mydatarc.working, codes = mydatarc.working$codes, dropList = list(lop
= 0), : object 'normalize' not found.
Below is what I did
require(pscl)
mydata<-read.csv(file.choose())
summary(mydata)
legNames<-mydata[,1]
pty1<-mydata[,2]
leg<-mydata[,3]
state<-mydata[,4]
const<-mydata[,5]
mydata <- mydata[, -c(1:5)]
summary(mydata)
mydatarc<-rollcall(mydata, yea=1, nay=0, missing=NA, notInLegis = 99,
legis.names=legNames, vote.names=NULL,
legis.data=NULL , vote.data=NULL)
summary(mydatarc)
summary(mydatarc,verbose=TRUE)
summary(mydatarc,verbose=TRUE)$lopsided
mydatarc.working <- dropRollCall(mydatarc,
dropList=list(lop=0))
summary(mydatarc.working)
idealobject<- ideal (mydatarc.working,
codes = mydatarc.working$codes,
dropList = list(lop=0),
d = 1,
maxiter = 10000,
thin = 100,
burnin = 5000,
impute = FALSE,
mda = FALSE,
normalize = TRUE,
meanzero = normalize,
priors = NULL,
startvals = "eigen",
store.item = TRUE,
file = NULL,
verbose=FALSE)
what am I doing wrong?
Thanks for your help,
Best,
Miriam
