========
[![Build Status](https://travis-ci.org/cosname/recharts.svg?branch=master)](https://travis-ci.org/cosname/recharts)A R interface to [ECharts](https://github.com/ecomfe/echarts) for data visualization.
文档请点击:
recharts 提供了百度开源可视化js框架Apache ECharts (incubating)的R语言接口,现提供的图形展示接口包括:地图(eMap),柱状图(eBar),折线图(eLine),
雷达图(eRadar),散点图(ePoints),漏斗图(eFunnel)以及万恶的饼图(ePie)。
同时计划对力导向图([eForce](http://echarts.baidu.com/demo.html#graph-force)),
时间序列散点图([ePoints_timeSeries](http://echarts.baidu.com/demo.html#graph-life-expectancy)),矩阵树图([eTree](http://echarts.baidu.com/demo.html#treemap-disk)),平行坐标图([eParallel](http://echarts.baidu.com/demo.html#parallel-aqi)) 和桑基图([eSankey](http://echarts.baidu.com/demo.html#sankey-energy))图逐一实现。# 安装 {#Installation}
部分 R 语言版本(R 3.2.2)会出现中文字符乱码,建议使用R语言版本为 `r R.version.string`。
recharts 包的源代码在 [Github](https://github.com/cosname/recharts) 上提供下载与安装,安装需要使用以下代码:
```{r, eval = FALSE}
remotes::install_github("cosname/recharts")
```# 图形模块
## 地图 {#eMap}
地图分别提供了世界地图、美国、中国地图以及各省级行政区地图,需要使用`region`参数进行地图显示地区的设置。
地图的使用需要由一个data.frame作为输入,包括了一列地名和多列数值,需要使用`~列名`的方式进行数值传递。
```{r}
library(recharts)
mapData <- data.frame(
province = c("上海", "江苏", "广东", "黑龙江"),
val1 = c(100, 200, 300, 500),
val2 = c(200, 300, 400, 200),
val3 = c(1, 2, 3, 5), stringsAsFactors = FALSE
)## 全国地图
eMap(mapData, namevar = ~province, datavar = ~ val1 + val2)
```![Map_China](screenshots/map_china.png)
```{r}
provinceMapData <- data.frame(
city = c("扬州市", "南京市", "苏州市"), value = c(100, 200, 300),
val2 = c(200, 300, 400), val3 = c(1, 2, 3), stringsAsFactors = FALSE
)
## 省份地图
eMap(provinceMapData, namevar = ~city, datavar = ~ value + val2, region = "江苏")
```![Map_Province](screenshots/map_province.png)
## 柱状图 {#eBar}
柱状图(eBar),允许3种类型的数据对象输入:
1. data.frame,需要指定`xvar=~weekDay; yvar= ~saleNum; series=~seller`,其中`series`参数可选。
```{r}
df2 <- data.frame(
saleNum = c(10, 20, 30, 40, 50, 60, 70, 15, 25, 35, 45,
55, 65, 75, 25, 35, 45, 55, 65, 75, 85),
seller = c(rep("小黄", 7), rep("小红", 7), rep("小白", 7)),
weekDay = c(rep(c("周一", "周二", "周三", "周四", "周五", "周六", "周日"), 3))
)
eBar(dat = df2, xvar = ~weekDay, yvar = ~saleNum, series = ~seller)
```![Barplot1](screenshots/barplot1.png)
2. 矩阵对象,以数据集 WorldPhones 为例,可以显示以行为X轴分度,列名为颜色分度,
矩阵数值为Y轴分度的柱状图。```{r}
class(WorldPhones)
WorldPhones
eBar(WorldPhones)
```![Barplot2](screenshots/barplot2.png)
3. table对象或因子(factor)数组
```{r}
library(recharts)
eBar(cut(rnorm(1000), -4:4))
```![Barplot3](screenshots/barplot3.png)
## 散点图 {#ePoints}
散点图需要的输入是 data.frame,需要指定 `xvar` 和 `yvar`,`series`为可选的颜色分度参数,
```{r}
# 测试下中文
iris$Species <- as.character(iris$Species)
iris$Species[1:20] <- "小红帽"
ePoints(iris, ~Sepal.Length, ~Sepal.Width, series = ~Species)
```![Scatterplot](screenshots/Scatterplot.png)
