Describe panel coverage and membership — panel

Classifies each organization on two axes – panel_type (boundary: persistent, entrant, exit, transient, empty) and panel_spell (continuity: seamless, segmented) – and summarizes the panel. See panel_label() to append the classification to rows and panel_filter() to select organizations.

Usage

panel_describe(x, ...)

# S3 method for class 'data.frame'
panel_describe(
  x,
  time = "TAX_YEAR",
  id = "EIN2",
  by_year = TRUE,
  print = TRUE,
  ...
)

# S3 method for class 'panel'
panel_describe(x, print = TRUE, ...)

Arguments

x: A panel data frame or a panel.
...: Passed to methods.
time: Name of the panel-time column.
id: Name of the panel-ID column.
by_year: Include the org-years-by-type breakdown. Default TRUE.
print: Print the summary. Default TRUE.

Value

For a data frame, invisibly a panel_summary object carrying the per-organization classification as its "classification" attribute; for a panel, the panel with labels refreshed.

Details

Given a panel it also stores the classification as label rules on the frame, marks the labels current, and logs the step.
