ManageData: Manage Data

Description

A GUI for managing, querying, and formatting data.

Usage

ManageData(cols, vars, parent = NULL)

Arguments

cols

list; see Value.

vars

list; see Value.

parent

tkwin; the GUI parent window.

Value

• Queries and sets the cols component of Data, a list whose length is equal to the current number of data variables. Each component in cols is linked to a specific variable, and contains the following components:
• name
  character; variable name.
• unit
  character; measurement units (optional); programmatic manipulation of measurement units is only supported for date and time variables.
• id
  character; a unique identifier that is created from a string concatenation of name and unit.
• fun
  character; the expression evaluated when computing the variables vector of values.
• index
  integer; the variables component index number in the data.raw data frame (see ImportData). Only required for variables directly linked to data columns in data.raw.
• class
  character; the data class of the vector object.
• digs
  integer; the precision of the variable, defined as the number of fractional digits or decimal places (optional).
• summary
  list; a summary of the variables descriptive statistics (see SummarizeData).
• comments
  character; user comments.
• The vars object is a list with components:
• x, y, z, t, vx, vy
  integer; the index number of the corresponding state variable in cols.
• The vars component of Data is only updated to reflect the removal and (or) reordering of variables (OpenRSurvey).

Details

This GUI lets you: (1) specify the names, measurement units, and decimal precision of variables; (2) add new variables based on user defined functions (see EditFunction); and (3) remove and (or) reorder variables in the data table.
