Data: Inspect (Return)ΒΆ
To view the Data Inspect page, go to the drop-down Data menu, select Inspect, and specify the key associated with the data.
The Data Indices or Header (if included when data were imported and parsed) display at the top of the page.
- Jump to Row
- To automatically move to a specified point in the data, enter an row index number and click the Jump to Row button.
- Info and Scrolling Buttons
- To display the front page and summary information, click info. Select any of the numbers displayed to jump to that page in the data.
- Change Type
- To specify how the data in a particular column should be treated (as numeric or as factors), click the buttons below the headers. If the data type that was automatically selected during data parsing is not the correct specification, change data type by clicking the button As Factor for integer columns, or reverse this change by clicking As Integer. Alphanumeric or alphabetical 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.
