Package: seasonalityPlot Type: Package Title: Seasonality Variation Plots of Stock Prices and Cryptocurrencies Version: 1.3.1 Authors@R: c(person("Satoshi", "Kume", role = c("aut", "cre"), email = "satoshi.kume.1984@gmail.com")) Description: The price action at any given time is determined by investor sentiment and market conditions. Although there is no established principle, over a long period of time, things often move with a certain periodicity. This is sometimes referred to as anomaly. The seasonPlot() function in this package calculates and visualizes the average value of price movements over a year for any given period. In addition, the monthly increase or decrease in price movement is represented with a colored background. This seasonPlot() function can use the same symbols as the 'quantmod' package (e.g. ^IXIC, ^DJI, SPY, BTC-USD, and ETH-USD etc).
