strucUPD.plot: Plot on Structure of Unbalanced Panel Dataset.

Description

strucUPD.plot Plot on cross-section and longtudinal structure of an object of class `data.frame` containing an unbalanced panel dataset.

Usage

strucUPD.plot(
  object,
  i.name = NULL,
  t.name = NULL,
  col.range = c("gold", "darkblue"),
  plot.name = "Unbalanced panel structure",
  ...
)

Value

Returns a plot for an unbalanced panel dataset contained in an object of class `data.frame` that visualizes the structure of the data. Cross-section dimension is plotted on the ordinate, longitudinal dimension on the abscissa. Each cross-sectional observation is represented by a bar. Breaks in the bars represent missing longitudinal observations.

Arguments

object

An object of class `data.frame`.

i.name

Column name of cross-section identifier.

t.name

Column name of time-series identifier.

col.range

A vector of at least two colors used to visualize the structure of the unbalanced panel data set (defaults to 'gold' and 'darkblue'); must be a valid argument to col2rgb.

plot.name

A vector indicating the title of the plot (defaults to 'Unbalanced panel structure').
