	C key, 
	Vector<T>^ values
)

member AddColumn : 
        key : 'C * 
        values : Vector<'T> -> DataFrame<'R, 'C> 

Parameters

key

Type: C
The key of the column.

values

Type: Extreme.MathematicsVectorT
The data for the column.

Type Parameters

T

Return Value

If values has a row index with the same element type as the data frame, a left join between the data frame's index and that index is used to determine the order of the elements of values in the new column.

If values has no index, or if the index has a different element type, all elements are added in the order provided. If the data frame has more rows than are present in values, missing values are appended. If the data frame has fewer rows, values is truncated.
