Extract latent process with standard error

Modeling
1

Hello all,

I have a latent process in my model and I want to extract the estimates + sd.
I know I can extract the estimates by

samples <- extract(fit,names)
h_std <- colMeans(samples$h_std[,1:n]),

but I do not know how to extract the standard error.
I know I have access to them in

I have only managed to extract h_std[1],h_std[2],…, but is there a way to extract all the h_std in one go?

Thanks!

sum_df = summary(fit)$summary
sum_df[startsWith(rownames(sum_df), "h_std"), ]

Should give you just the rows that have h_std info in them. If you only want se_mean in those rows, you could do:

sum_df[startsWith(rownames(sum_df), "h_std"), "se_mean"]

That what you were looking for?
