drop_parameters: Drop parameters from a 'shinystan' object

In shinystan: Interactive Visual and Numerical Diagnostics and Posterior Analysis for Bayesian Models

Drop parameters from a shinystan object

Description

Remove selected parameters from a shinystan object. This is useful if you have a very large shinystan object when you only want to look at a subset of parameters. With a smaller shinystan object, launch_shinystan will be faster and you should experience better performance (responsiveness) after launching when using the 'ShinyStan' app.

Usage

drop_parameters(sso, pars)

Arguments

sso	A shinystan object.
pars	A character vector of parameter names. If the name of a non-scalar (e.g. vector, matrix) parameter is included in pars all of its elements will be removed. Currently it is not possible to remove only a subset of the elements of a non-scalar parameter.

Value

sso, with pars dropped.

See Also

generate_quantity to add a new quantity to a shinystan object.

Examples

# Using example shinystan object 'eight_schools'
print(eight_schools@param_names)

# Remove the scalar parameters mu and tau
sso <- drop_parameters(eight_schools, pars = c("mu", "tau"))
print(sso@param_names)

# Remove all elements of the parameter vector theta
sso <- drop_parameters(sso, pars = "theta")
print(sso@param_names)
