Installation

The package is available on CRAN. The full installation can be obtained with:

install.packages("echarts4r")

However, if you only want a lite version you can simply do, this is useful for a lighter version that installs faster if you do not want to use any of the geospatial features of the package:

install.packages("echarts4r", dependencies = c("Depends", "Imports"))

You can also install the unstable development version of echarts4r with remotes from Github, see changes.

# install.packages("remotes")
remotes::install_github("JohnCoene/echarts4r")

如果您位于中国，请安装:

# install.packages("remotes")
remotes::install_git("https://gitee.com/JohnCoene/echarts4r") # gitee

Example

Create multiple charts, arrange them in a grid and connect their interactions; this is nonsensical chart for demonstration purposes.

library(dplyr)
library(echarts4r)
library(echarts4r.assets)

e1 <- iris %>% 
  group_by(Species) %>% 
  e_charts(
    Sepal.Length,
    elementId = "chart"
  ) %>% 
  e_scatter(Petal.Length, Sepal.Width) %>% 
  e_datazoom(show = FALSE, y_index = 0) %>% 
  e_x_axis(min = 4) %>%  
  e_highlight(
    series_name = list("setosa", "versicolor", "virginica"),
