To declare an svector object, use the keyword svector, followed by a name.

clears the custom column label from the svector SVEC1.

See also Svector::clearrowlabels.

Removes the svector history attribute, as shown in the label view of the svector.

The first line removes the history from the svector S1, and the second line displays the label view of S1, including the now blank history field.

See “Labeling Objects” for a discussion of labels and display names.

See also Svector::label.

Removes the svector’s remarks attribute, as shown in the label view of the svector.

The first line removes the remarks from the svector S1, and the second line displays the label view of S1, including the now blank remarks field.

See “Labeling Objects” for a discussion of labels and display names.

See also Svector::label.

clears the custom row labels from the svector SVEC1.

See also Svector::clearcollabels.

Creates either a named or unnamed copy of the svector.

creates an unnamed copy of the svector S1.

creates S2, a copy of the svector S1.

See also copy.

Display the contents of a table, graph, or spool in the window of the svector object.

Display the contents of the table TAB1 in the window of the object SVECTOR1.

Most often used in constructing an EViews Add-in. See “Custom Object Output”.

Attaches a display name to an svector object which may be used to label output in place of the standard object name.

Display names are case-sensitive, and may contain a variety of characters, such as spaces, that are not allowed in svector object names.

The first line attaches a display name “List of Names” to the svector object SVEC1, and the second line displays the label view of SVEC1, including its display name.

See “Labeling Objects” for a discussion of labels and display names.

See also Svector::label.

Follow the keyword with a name for the file. file_name may include the file type extension, or the file type may be specified using the “t=” option.

If an explicit path is not specified, the file will be stored in the default directory, as set in the File Locations global options.

The base syntax for writing Excel 2007 files is:

where the table_description may contain:

If the worksheet name contains spaces, it should be placed in single quotes. If the worksheet name is omitted, the cell range is assumed to refer to the currently active sheet. If only a top left cell is provided, a bottom right cell will be chosen automatically to cover the range of non-empty cells adjacent to the specified top left cell. If only a sheet name is provided, the first set of non-empty cells in the top left corner of the chosen worksheet will be selected automatically. As an alternative to specifying an explicit range, a name which has been defined inside the Excel workbook to refer to a range or cell may be used to specify the cells to read.

The command:

exports data in SVECTOR1 to a CSV file named “mysvector.CSV” in the default directory.

saves the contents of SVECTOR1 along with the column and row headers to a CSV (comma separated value) file named “mysvector.CSV” and writes all NA values as “NaN”.

writes the data of SVECTOR1 along with the column and row headers to a HTML file named “mysvector.HTM” at half of the original size.

exports the data in the second column to a CSV file named “mysvector.CSV”, and writes all NA values as “.”.

writes the data in SVECTOR1 to the preexisting “mysvector.XLSX” Excel file to the “Country” sheet at cell B5, where all cell formatting is cleared.

See Svector::import.

Follow the keyword with a list of strings to place in the svector object. Each value should be surrounded by double quotes if necessary, and values should separated by a space. Running out of values before the object is completely filled is not an error; the remaining cells or observations will be unaffected, unless the “l” option is specified to enable looping. If, however, you list more values than the object can hold, EViews will return an error message.

sets the first element of SV1 to “a”, the second to “B” and the third to “c”.

sets the second element of SV1 to “a”, the third to “Hello World” and the fourth to “name”.

sets the fourth element of SV1 to “first”, the fifth to be an empty string, and the sixth value to “Last”, then repeats the same three values for the remaining rows, so that the seventh element is set to “first”, the eight element is empty, the ninth set to “Last” and so on.

clears all of the values in the svector SV1.

An alternative approach to filling the elements of an svector uses the @sfill function to create a new svector in a single line, as in

See “Matrix Language” for a detailed discussion of vector and matrix manipulation in EViews.

freq performs a one-way frequency tabulation.

Frequencies are computed for all of the rows in the svector. Rows with missing values (blanks) are dropped unless included by option. You may use options to control the order of the entries of the table.

tabulates each value of SVEC1 in ascending alphabetical order with counts, percentages, and cumulatives.

tabulates the values of SVEC1 including NAs.

tabulates SVEC1 with the table rows ordered from values with highest frequency to lowest.

See “One-Way Tabulation” for a discussion of frequency tables

The syntax for reading Excel files is:

The following table_description elements may be used when reading Excel data:

The optional variables_description may be formed using the elements:

loads the active sheet of DATA.XLSX into the SVEC_NAME svector object.

reads the data contained in the “GDP data” sheet of “Data.XLS” into the SVEC_OBJ object.

The syntax for reading HTML pages is:

The following table_description elements may be used when reading an HTML file or page:

The optional variables_description may be formed using the elements:

loads into the SVEC1 svector object the data located in the HTML file “Data.HTML” located on the C:\ drive

loads into an svector object called SVEC1 the data with the given URL located on the website site “http://www.tradingroom.com.au”. The column header is set to three rows.

The syntax for reading text or binary files is:

If a table_description is not provided, EViews will attempt to read the file as a free-format text file. The following table_description elements may be used when reading a text or binary file:

A central component of the table_description element is the format statement. You may specify the data format using the following table descriptors:

The optional variables_description may be formed using the elements:

reads “Data.CSV” into SVEC2, skipping the first 5 rows.

loads the comma delimited data DATE.TXT into the SVEC01 svector object.

See Svector::export.

To modify the label, you should specify one of the following options along with optional text. If there is no text provided, the specified field will be cleared:

The following lines replace the remarks field of the string S1 with “Name of Dependent Variable from EQ3”:

See “Labeling Objects” for a discussion of labels.

See “Object Linking and Embedding (OLE)” for a discussion of using OLE with EViews.

resizes the svector SVEC1 to 20 rows, retaining the contents of any existing elements and initializing new elements to the empty string “”.

See also Svector::fill.

Sets the attribute attr to attr_value. Note that quoting the arguments may be required. Once added to an object, the attribute may be extracted using the @attr data member.

sets the “revised” attribute in the object A to the string “never”, and extracts the attribute into the string object S.

See “Adding Custom Attributes in the Label View” and “Adding Your Own Label Attributes”.

Follow the setcollabels command with the column label. Note that the column label should not contain spaces unless it is enclosed in quotes.

sets the column label to “MyResults”.

See also Svector::setrowlabels.

Follow the setrowlabels command with a space delimited list of row labels. Note that each row label should not contain spaces unless it is enclosed in quotes. If you provide fewer labels than there are rows, EViews will keep the corresponding default row names (“R11”, “R12”, etc...).

sets the row label for the first row in svector SVEC1 to USA, the second to UK, and the third to FRANCE.

See also Svector::setcollabels.

displays the spreadsheet view of S01.

where mode is either 0 or 1 where 0 displays the default row and column labels and 1 displays the custom row and column labels (if present).

displays the custom row and column labels for the S1 spreadsheet. If custom labels have not been set the default labels will be displayed.

displays the default row and column labels for the S1 spreadsheet.

See Svector::setcollabels and Svector::setrowlabels.

The svector command declares a string vector object.

The svector keyword should be followed by a valid name. n is an optional length for the vector. If n is not provided, the resulting svector will be one element long.

declares a string vector object named ALPHAVEC containing no text.

declares a 20 element svector.

See “Strings” and “String Vectors” for a discussion of strings and string vectors.
