some problems about how to do a 3-step approach with tidyLPA in R

[Alisa]

Hi, 

I am using tidyLPA to finish my research, but I have some problems about produces after getting the latent profiles outcome. More specifically, I'd like to know how to run a 3-step approach in R after using the "estimate_profiles". 

I find I could get the probability for each sample in CPROB* by using the code "get_data". I guess I could add these CPROB* as weights in the logit model, but I don't know how to add several weights in one logit model and I am not sure whether my assumption is right actually. Could you provide my some help?

Best,

Alisa
