Examples

  ## Not run: 

# Simple example. 
MAP(z_ig_random_soft(100,2))

# import dataset. 
data(x2)
mm <- gpcm(data = as.matrix(x2),G = 1:7,
           start = 2,
           veo = FALSE,pprogress=FALSE)

best = get_best_model(mm)
# You can get labels using the internal object with MAP.
labs <- MAP(best$model_obj[[1]]$zigs)
# or you can just get labels directly. 
labs2 <- best$map
  
## End(Not run)
