To install this package, it is the easist to install devtools
package first:
install.packages("devtools")
Now load the package using library()
library(devtools)
Then we can use the install_github
to get the package directly:
install_github("kochiuyu/CandleStickPattern")
Finally, we load the package using library()
library(CandleStickPattern)
You can see the details of how each function works in vignette
The following demonstrates the usage of the function doji()
using Microsoft (ticker: MSFT). We use quantmod package to download data:
library(quantmod)
getSymbols("MSFT", from = "2011-07-08" , to = "2011-07-19")
We first plot the candle chart first:
candleChart(MSFT,theme='white')
We can see that July 11, 12, 13, and 18 are likely to follow doji pattern. Let us see if we can capture using the function doji
:
doji(MSFT)
## doji
## 2011-07-08 FALSE
## 2011-07-11 TRUE
## 2011-07-12 TRUE
## 2011-07-13 TRUE
## 2011-07-14 FALSE
## 2011-07-15 FALSE
## 2011-07-18 TRUE
## 2011-07-19 FALSE
