bootstrap unavailable for clmm

[smaistre]

When I use the bootstrap option on the example proposed in the ordinal::clmm documentation, I get the following error

Error in [.data.frame(params, match(colnames(params_variance), colnames(params))) : undefined columns selected

library(ordinal)
fmm1 <- clmm(rating ~ temp + contact + (1|judge), data = wine)	
model_parameters(
  fmm1,
  bootstrap=TRUE,
  iterations = 100
)
