list.table.chart {textreg}

Graphic showing multiple word lists side-by-side.

Description

This method basically makes a visual plot of a list table (which you call first).

Usage

list.table.chart(model.list, M = 100, linespace = 4, ytick = NULL,
  dates = NULL, main = paste("Word Appearance for ", attr(model.list,
  "topic"), "\n(Method: ", attr(model.list, "method"), ")", sep = ""),
  xlab = "Model", mar = c(3, 5, 2.5, 0.1), xaxt = "y",
  color.breaks = NULL, color.ramp = NULL, ...)

Arguments
