Error in sfreemap()

[MarliesJFrancine]

When I run sfreemap() I get this error message:
Error in colnames<-(*tmp*, value = lvls) :
attempt to set 'colnames' on an object with less than two dimensions
In addition: Warning message:
In apeAce(bt, xx, model, omp, fixedQ = Q, output.liks = liks) :
model fit suspicious: gradients apparently non-finite

I am unsure of what causes this, is there someone who has encountered this before?

Hi there, could you please share some more information?

1. The full command line you are trying to run. If possible please share the inputs as well.
2. What is your operating system and R version.

Thank you.
