General Functions

Top level functions that can be called from the Danfo namespace

Data transformation
​merge​
Merge DataFrame or named Series objects with a database-style join.
​concat​
Concatenate danfo objects along a particular axis with optional set logic along the other axes.
​getDummies​
Convert categorical variable into dummy/indicator variables. Similar to OneHotEncoding
Data Normalization
​LabelEncoder​
Encode target labels with value between 0 and n_classes-1.
​OneHotEncoder​
Encode categorical features as a one-hot numeric array.
​StandardScaler​
Standardize features by removing the mean and scaling to unit variance
​MinMaxScaler​
Transform features by scaling each feature to a given range
Working with DateTime
​toDateTime​
Convert argument to datetime.
​dateRange​
Return a fixed frequency Datetime Index.
​Dt​
A class that converts strings of Date Time into a usable format, by exposing various helper methods.
Streaming Functions
​streamCSV​
A function that loads a CSV object as a stream, returning intermediate rows as a DataFrame.
​streamJSON​
A function that loads a JSON object as a stream, returning intermediate rows as a DataFrame.
​streamCSVTransformer​
A function that loads a CSV object as a stream, and applies a map-reduce function to intermediate rows.
​convertFunctionTotransformer​
A function to convert any JS function into a Stream transformer.
Utility and Configurations
​Utils​
A utility class with helper methods mostly used internally.
​Config​
Base configuration class for NDframe objects
Strings
​Str​
A class that converts strings into a usable format, by exposing various helper methods.
Internal Libs
​tensoflow​
Exported Tensorflow.js library. This helps to avoid duplicated Tensorflow.js library use.
