I would like to use the ideal() function in the pscl
package in R
. When I run the example provided in the help file, i.e.,
data(s109)
n <- dim(s109$legis.data)[1]
x0 <- rep(0,n)
x0[s109$legis.data$party=="D"] <- -1
x0[s109$legis.data$party=="R"] <- 1
id1 <- ideal(s109,
d=1,
startvals=list(x=x0),
normalize=TRUE,
store.item=TRUE,
maxiter=260E3,
burnin=10E3,
thin=100)
I receive the following error message:
Error in .C("IDEAL", PACKAGE = .package.Name, as.integer(n), as.integer(m), :
wrong type for argument 18 in call to IDEAL
How can I solve this? Thanks in advance.
P.S.: I'm on OS X 10.13, using R 3.4.2 and pscl 1.5.1.
The problem is resolved with the new version of the pscl
package (version 1.5.2), which has been released on 2017-10-10.
