Obtain Column Names

Column Name(n) returns the name of the n th column.

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

Column Name( 2 );

age

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

Column Name( 2 )[1];

Char( Column Name( 2 ) );

"age"

dt << Get Column Names( argument );

where the optional argument controls the output of the Get Column Names function, as follows:

•

Specify Numeric, Character, Row State, or Expression to include only those column data types.

•

Specify "Continuous", "Ordinal", or "Nominal" to include only those modeling types.

•

Specify String to return a list of strings rather than column names.

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

names = dt << Get Column Names(Numeric, "Continuous")
