R is `GNU S', a freely available language and environment for statistical computing and graphics which provides a wide variety of statistical and graphical techniques: linear and nonlinear modelling, statistical tests, time series analysis, classification, clustering, etc. Please consult the R project homepage for further information.
補充R的好處,它可以支援繁體中文,另外也支援csv格式(盤後資料是csv),詳細語法在R視窗中打: ?read.csv 就可以了解了!
R應用在Stock: 1. 下載盤後資料 2.處理OHLC&volume 3.利用xts & quantmod 可自動將日資料轉成週及月資料(一個指令即可) 4.利用package可計算各種指標 5.加入自已選股的條件 6. 背景下執行~
