pedquant (Public Economic Data and QUANTitative analysis) provides an interface to access public economic and financial data for economic research and quantitative analysis. The functions are grouped into three main categories,

  • ed_* (economic data) functions load economic data from NBS and FRED;
  • md_* (market data) functions load the forex, money, bond, stock, future market data from public data sources, including 163, Sina, qq finance and etc.
  • pq_* (quantitative analysis) functions create technical indicators, visualization charts and industrial index etc for time series data.

The functions in this package are designed to write minimum codes for some common tasks in quantitative analysis process. Since the parameters to get data can be interactively specify, it’s very easy to start. The loaded data have been carefully cleansed and provided in a unified format.

pedquant package has advantages on multiple aspects, such as the format of loaded data is a list of data frames, which can be easily manipulated in data.table or tidyverse packages; high performance on speed by using data.table and TTR; and interactive charts by using echarts4r. Similar works including tidyquant or quantmod.
