For example : df <- data.frame( var = c("low","low","low","high") ) i want the same result as ggplot(df)+geom_bar(aes(var)).

Answer 1

First you need to create a dataframe which shows the count per var and after that you can use this in e_chart with e_bar like this:

df <- data.frame( var = c("low","low","low","hight") )
library(dplyr)
library(echarts4r)

df_result <- df %>% 
  count(var) %>% 
  arrange(n)

plot <- df_result %>%
  e_charts(x = var) %>%
  e_bar(n, legend = FALSE, name = "var")

Output:

Which is the same result using ggplot:

ggplot(df)+geom_bar(aes(var))
