Good morning everyone,

I am running into errors with poLCA as follows:

Error in round(mf) : non-numeric argument to mathematical function.

Here is what I have. Both variables are coded as 1, 2, 3

df <- as.data.frame(data)

items <- c("x1", "x2")  <- there are more variables but shortened for this

df2 <- df[items]

i <- cbind(x1, x2)~1

poLCA (i, df2, nclass=2, maxiter=100, nrep=10, verbose =TRUE)

It is after the poLCA that I get the error. Any thoughts on what is causing
