grid_trace2 {spam}

Two trace plots and a scatter plot.

Description

For two (MCMC) chains of the same length trace plots and a scatter plot are drawn.

Usage

grid_trace2(chain1, chain2 = NULL,
            xlim = NULL, ylim1 = NULL, ylim2=NULL,
            chain1_lab = "", chain2_lab = "", main = "",
            chain1_yaxis_at = NULL, chain2_yaxis_at = NULL,
            log = FALSE,
            cex_points = unit(0.2, "mm"),
            cex_main = unit(1.2, "mm"),
            lwd_lines = unit(0.1, "mm"),
            lwd_frame = unit(0.8, "mm"),
            draw = TRUE)

Arguments

chain1

Numeric vector or a matrix with two columns.

chain2

Numeric vector of same length as chain1. (Only used if chain1 is specified as vector).

xlim

x axis limits of both chains (numeric vector of length 2).

ylim1

y axis limits of chain 1 (numeric vector of length 2).

ylim2

y axis limits of chain 2 (numeric vector of length 2).

chain1_lab

Label of chain 1 (character of length 1).

chain2_lab

Label of chain 2 (character of length 1).

main

Title (character of length 1).

chain1_yaxis_at

Points at which tick-marks are drawn for chain 1.

chain2_yaxis_at

Points at which tick-marks are drawn for chain 2.

log

Logical, should the date be log transformed?

cex_points

Size of points in scatter plot.

cex_main

Size of the title font.

lwd_lines

Line width of trace plots.

lwd_frame

Line width of frames.

draw

Logical, should the returned grob object be drawn?

Details

The figure is optimized for a plot of the format x11(width = 10, height = 3).

Value

A grob object.
