## 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 |

`comp.label` |
vector of component labels (positive integers, e.g., |

`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)
```
