Dataplot Vol 2 Vol 1

DIGITS TO STRING

Name:
    DIGITS TO STRING
Type:
    Let Subcommand
Purpose:
    Convert a vector of positive integers to a string.
Description:
    Given a vector that contains the values 2, 3, and 5, the DIGITS TO STRING command creates the string

      X2*X3*X5

    This is a utility routine used by the macros that run the 10-step analysis of 2-level factorial designs.

    Dataplot will add 0.5 to the numbers in the vector and then take the absolute value before truncating to the integer value.

Syntax:
    LET <sout> = DIGITS TO STRING <y>
    where <sout> is the name of the resulting string;
    and     <y> is a variable containing integer values.
Examples:
    LET SOUT = DIGITS TO STRING Y
Note:
    The name on the right hand side of the equal sign must be a previously existing variable. If it is a previously existing parameter, string, or matrix name, an error will be reported and the requested string will not be created.

    The name on the left hand side of the equal sign may be a previously existing string. However, if it is a previously existing parameter, variable, or matrix name, an error will be reported and the requested string will not be created.

Note:
    The total number of characters that DATAPLOT can use for storing functions and strings is set when DATAPLOT is built. The current default (11/2008) is 50,000 characters. Previous versions may set this limit at 1,000 or 10,000 characters. This limit applies to the combined number of characters for all functions and strings.
Default:
    None
Synonyms:
    None
