Plot TDMM posterior traces

plot.trace.tdmm.Rd

Display chain-specific traces for monitored posterior parameter names.

Usage

# S3 method for class 'tdmm'
plot.trace(result, params, file = NULL, ncol = 2, width = 1800, height = NULL, res = 150, lwd = 0.4, col = NULL, 
    show.legend = FALSE, cex.axis = 0.85, cex.lab = 0.9, cex.main = 1)

Arguments

result

A fitted tdmm object.

params

Character vector of monitored parameter names.

file

Optional PNG output path.

ncol

Number of plot columns.

width

PNG width in pixels.

height

PNG height in pixels; computed automatically if NULL.

res

PNG resolution.

lwd

Trace line width.

col

Optional chain colors.

show.legend

Whether to show chain legend.

cex.axis

Axis text scaling.

cex.lab

Axis-label scaling.

cex.main

Title scaling.

Details

Parameter names must match the fitted posterior matrix exactly. For example, "sigma.b" is random-effect standard deviation and "sigma2.b" is variance. Spline smoothing parameters have names such as "tau.alpha[1]".

Value

Creates trace plots; returns invisibly.
