We are excited to announce the nse2r package. NSE (National Stock Exchange) is the leading stock exchange of India, located in the city of Mumbai. While users can manually download data from NSE through a browser, importing this data into R becomes cumbersome. The nse2r R package implements the retrieval of data from NSE and aims to reduce the pre-processing steps needed in analyzing such data.

nse2r is inspired by and a port of the Python package nsetools. The authors and contributors for this R package are not affiliated with NSE and NSE does not offer support for this R package.

With nse2r, you can fetch the following data related to:

Installation

# Install release version from CRAN
install.packages("nse2r")

# Install development version from GitHub
# install.packages("devtools")
devtools::install_github("rsquaredacademy/nse2r")

Usage

nse2r uses consistent prefix nse_ for easy tab completion.

  • nse_index_ for index
  • nse_stock_ for stocks
  • nse_fo_ for futures and options
  • nse_preopen_ for preopen data

Preprocessing

nse2r does basic data preprocessing which are listed below:

  • modify column data types from character to numeric and Date
  • modify column names
    • make them more descriptive
    • to snake_case from camelCase

Users can retain the names and format as returned by NSE using the clean_names argument and setting it to FALSE.
