init(column:)

Creates a new column of integers from a given column whose elements can be converted to integers.

Declaration

init<T>(column: MLDataColumn<T>) where T : MLDataValueConvertible

Parameters

column:
An Mldatacolumn of elements convertible to Int.

Discussion

Use this initializer to create a column of integers from another column. Start by creating a column that is convertible to a column of integers.

let stringsColumn = MLDataColumn(["1", "2", "3", "4", "5"])
print(stringsColumn) // Prints ["1", "2", "3", "4", "5"]

Then use init(column:) to convert the column to a column of integers.

let intsColumn = MLDataColumn<Int>(column: stringsColumn)
print(intsColumn) // Prints [1, 2, 3, 4, 5]
