This is an rCharts binding for the excellent Cal-Heatmap plugin, developed by Wan Qi Chen. This binding was motivated by a tweet by Alex Bresler and uses data provided by him on points scored by Paul George.
You can install it from github
using devtools
.
library(devtools)
install_github("ramnathv/rCharts")
install_github("ramnathv/rChartsCalendar")
Let us start with some data on points scored by Paul George.
dat <- read.csv('http://t.co/mN2RgcyQFc')[,c('date', 'pts')]
library(rChartsCalendar)
r1 <- plotCalMap(x = 'date', y = 'pts',
data = dat,
domain = 'month',
start = "2012-10-27",
legend = seq(10, 50, 10),
itemName = 'point',
range = 7
)
Here is another example showing stock price of APPLE.
library(quantmod)
getSymbols("AAPL")
xts_to_df <- function(xt){
data.frame(
date = format(as.Date(index(xt)), '%Y-%m-%d'),
coredata(xt)
)
}
dat = xts_to_df(AAPL)
plotCalMap('date', 'AAPL.Adjusted',
data = dat,
domain = 'month',
legend = seq(500, 700, 40),
start = '2014-01-01',
itemName = '$$'
)
