Data: Inspect (Return)
========================

The Data Inspect page is accessed by going to the **Data** drop down
menu, selecting **Inspect** and specifying the key associated with the
data to be examined. 

Data Indices or Header (if included when data were imported and
parsed) are displayed across the top of the page. 

**Jump to Row**
  Users can automatically move to a specified point in the data by
  entering an row index number and pressing the **Jump to Row**
  button. 

**Info and Scrolling Buttons**
  Selecting Info returns the front page and summary
  information. Selecting any one of integer numbers displayed across
  the top will take the user to that page in the data.

**Change Type** 
  Users may wish to specify whether the data in a particular column
  should be treated as numeric or as factors. Where the default
  assumption about the data does not reflect the correct specification
  users can change data type by clicking the button **As Factor** in
  integer columns, or reverse this change by clicking **As Integer**. 
  Alpha-numeric or alpha data are automatically classified as factor
  data, and cannot be treated as numeric, and continuous real data
  cannot be converted to factor data because the number of possible
  factor levels is infinite. 

**Type** 
  Specifies the type of data contained in a column. 
  *Int*: Integer; discrete numeric data (1, 2, 3, 4, ...)
  *Real*: Continuous real data (1, 1.01, 1.1, 1.3, 1.55, ...)
  *Enum*: Enumerative, Factor or Categorical data. (Red, Green, Blue,
  ...)

**Min**
  The minimum value in a column of numeric data. 

**Max**
  The maximum value in a column of numeric data. 

**Mean** 
  The average value of the data in a numeric column. 

**Cardinality** 
  The number of unique levels in a column of factor data. 

**Missing**
  The number of missing values in a column of data.
