Data: Inspect (Return)ΒΆ
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.
