Dataframe.merge(...)
This function adds both columns and rows to the dataframe, ie. it adds new labels to the dataframe and if one dataframe is larger than the other, then it adds in those rows with empty values ie. null
This function merges two different dataframe together, ie. dataframe with different type or labels, assuming the
first dataframe has a type K and the second a type of B
Parameter
Dataframe- of typeB, whereBis your type
Returns
Dataframe<K & B>
The example below merges two dataframe with the different type; where df and new_df are dataframes of type K & B
const concat: Dataframe<K & B> = df.merge(new_df);The merge function implicit determines the type of K and B if it has been passed to the Breadroll.open functions, but you can explicitly provide the types to the merge function like so df.merge<A, B>(new_df) where A is the type of df and B is the type of new_df
