Recode Options
In Place
applies any change to the original data column.
New Column
creates a new column for the changed data and retains the original column.
Formula Column
creates a new column with the changes as a formula instead of values.
Script creates a new script called Recode in the data table. You can run this script to perform recoding
in-place. If you add more recodes later, the script updates (assuming that you select Script as the
destination). You can run this script later, to new data, and copy it to other data tables, or run it from
your own scripts.
Red Triangle Options for Recode
The red triangle menu contains options for the Recode window. The first three commands apply to all items
in the data table list.
Convert to Titlecase converts to title case, that is, an initial uppercase character and subsequent
lowercase characters for each word.
Convert to Uppercase
converts all items to uppercase.
Convert to Lowercase converts items to lowercase.
Tab characters, space characters, and line separators are often imported into a data table. Remove these
characters using the following commands:
Trim Whitespace removes leading and trailing whitespace characters. For example, if an extra space was
imported before and after the name John, this command would delete the spaces.
