That is, you can create multiple access descriptors, as well as one or more view descriptors based on these access descriptors, within the same execution of the ACCESS procedure. Range names can be up to 15 characters long and are not case-sensitive.
Next, specify any editing statements: First, create the access descriptor as described in Creating access descriptors except omit the RUN statement.
NO, the default, treats any data in a column that does not match the specified type as missing values. After you correct the errors, resubmit your statements. If errors are found, error messages are written to the SAS log, and Wk4 assign is terminated.
Information from database-description statements is stored in an access descriptor. A worksheet letter is a one- or two-letter alpha character. Therefore, you do not repeat this information when you create view descriptors. The third part is the descriptor type. These statements must be placed before any editing statements.
If you specify a range name, the name must have been previously defined in the WKn file. You use it if you have both Lotus numeric and character data in a column. Worksheet names can be up to 15 characters long and are not case-sensitive.
Altering a PC file that has descriptor files defined on it may cause the descriptor files to be out-of-date or invalid. The descriptor name has three parts, separated by periods. Or, you can create access descriptors and view descriptors in separate executions of the procedure. The default value is A.
The skipped or ignored rows often contain information such as column labels or names or underscores rather than input data. The range-address is identified by the top left cell that begins the range and the bottom right cell that ends the range within the WKn worksheet file.
Finally, specify the RUN statement.
The MIXED statement is an editing statement and must follow any database descriptions when you create an access descriptor. The order of the statements within the database-description and editing groups sometimes matters; see the individual statement descriptions for more information.
Do not specify these statements when you create view descriptors. You can change as many database field types as you want in one TYPE statement.
See Setting Environment Variables for more information on setting and changing environment variables. The range-name is the name that is assigned to a range address within the worksheet. For example, if you re-create a file and add a new column to the file, an existing access descriptor defined on that file does not show that column; in this case, the descriptor may still be valid.
To access a particular PC file of a supported type, you must create first an access descriptor, and then one or more view descriptors based on the access descriptor. By default, SAS variable formats are generated from the formats found in the first row of the worksheet or in the range of the worksheet if you specified a range.
If no errors are found when the RUN statement is processed, all descriptors are saved. It also creates a view descriptor named VLIB. This information describes the location and characteristics of the PC file. Finally specify the RUN statement. See Chapters 5 and later for additional database-description statements for your PC file format.
The order of the statements within this group usually does not matter; see the individual statement descriptions for any restrictions. F12 indicates a cell range that begins at cell C9, ends at cell F12, and includes all cells in between. The descriptor-name is the name of the descriptor to Wk4 assign created.
For WK3 and WK4 files, there can be up to different worksheet letters: For WK1 files, there is only one worksheet letter:Use CREATE to create an access or view descriptor for a PC file you want to access from the SAS system. To access a particular PC file of a supported type, you must create first an access descriptor, and then one or more view.
The graph at the right is a sample plot from the Shiny Application in the case when the user selects 'wt' for the x-axis, 'mpg' for the y-axis, and 'cyl' for the color. The ASSIGN statement indicates whether SAS variable names and formats are automatically generated. Where long names must be shortened to the SAS length limit of eight characters, variable names are automatically generated.
