paramtrace {BAMBI}

Trace plot for parameters from an angmcmc object

Description

Trace plot for parameters from an angmcmc object

Usage

paramtrace(object, par.name, comp.label, chain.no, ...)

Arguments

object

angular MCMC object.

par.name

vector of names of parameters for which point estimates are to be computed. If NULL, results for all parameters are provided.

comp.label

vector of component labels (positive integers, e.g., 1, 2, ...) for which point estimates are to be computed. If NULL, results for all components are provided.

chain.no

vector of chain numbers whose samples are to be be used. in the estimation. By default all chains are used.

...

unused

par

parameter for which trace plot is to be created.

Value

Returns a single plot if a single par and a single comp.label is supplied. Otherwise, a series of plots is produced.

Examples

# first fit a vmsin mixture model
# illustration only - more iterations needed for convergence
fit.vmsin.20 <- fit_vmsinmix(tim8, ncomp = 3, n.iter =  20,
                             n.chains = 1)
# trace plot for kappa1 in component 1
paramtrace(fit.vmsin.20, "kappa1", 1)
# for kappa1 in all components
paramtrace(fit.vmsin.20, "kappa1")
# for all parameters in component 1
paramtrace(fit.vmsin.20, comp.label = 1)
