AlphaVantageQuery

The goal of AlphaVantageQuery is to query the API from Alpha Vantage (which you can find at: https://www.alphavantage.co/) for easy access to data. All you would need is a ticker symbol and an API key for more granular level data.

Installation

You can install the released version of AlphaVantageQuery from CRAN with:

install.packages("AlphaVantageQuery")

Example

This is a basic example which shows you how to solve a common problem:

library(AlphaVantageQuery)


alpha_vant("GOOGL", frequency = "daily")      # this only returns a data frame

matrix1 = matrix(
    c(
      rep(1,3),
      rep(1,3),
      rep(1,3),
      rep(2,3),
      rep(2,3)
    ), 
    nrow = 5, ncol = 3, byrow = TRUE
  )
  with(subset(GOOGL_DAILY, GOOGL_DAILY$date > as.Date("2010-01-01")),
       {
         layout(matrix1)
         plot(date, open, type = "l", main = "GOOGL")
         lines(date, high, col = "blue", lwd = 0.3)
         lines(date, low, col = "blue", lwd = 0.3)
         
         plot(date, volume, type = "l", main = "GOOGL", col = "#108a4c")
       }
  )

Note that the function only returned the data frame.
