def ++(other: Frame): Frame

Joins two frames together, such that the elements of the given frame are appended to the end of this frame.
Joins two frames together, such that the elements of the given frame are appended to the end of this frame. This operation is the same as a concat operation.

def addField(field: Field, defaultValue: Any): Frame

Returns a new Frame with the given field added at the end.
Returns a new Frame with the given field added at the end. The value of this field for each Row is specified by the default value. The value must be compatible with the field definition. Eg, an error will occur if the field had type Int and the default value was 1.3
def addField(name: String, defaultValue: Any): Frame

Returns a new Frame with the new field of type String added at the end.
Returns a new Frame with the new field of type String added at the end. The value of this field for each Row is specified by the default value.

For each row, the value corresponding to the given fieldName is applied to the function.
For each row, the value corresponding to the given fieldName is applied to the function. The result of the function is the new value for that cell.
def replace(fieldName: String, from: String, target: Any): Frame

Replaces any values that match "form" with the value "target".
Replaces any values that match "form" with the value "target". This operation only applies to the field name specified.
def replace(from: String, target: Any): Frame

Foreach row, any values that match "from" will be replaced with "target".
Foreach row, any values that match "from" will be replaced with "target". This operation applies to all values for all rows.
def replaceNullValues(defaultValue: String): Frame
def sample(k: Int): Frame

Returns a new Frame where only each "k" row is retained.
Returns a new Frame where only each "k" row is retained. Ie, if sample is 2, then on average, every other row will be returned. If sample is 10 then only 10% of rows will be returned. When running concurrently, the rows that are sampled will vary depending on the ordering that the workers pull through the rows. Each stream (thread) uses its own count for the sample.
