I have a data frame about voices and emotions. Using shiny I want to create a scatter plot graph with a tooltip which shows the name and type of emotions and runs the audio file. When people click on a point, I want to hear the audio of this emotion. However, I cannot find any solution to run an audio file. Audio files in wav format. Basically, I want to know how I add audio files into hoover or tooltip. I used hchart package for create graph.
This is server part of my shiny app
require(shinydashboard)
require(ggplot2)
require(dplyr)
require(highcharter)
library(readxl)
require(tidyr)
server <- function(input, output) {
output$hcontainer <- renderHighchart ({
data_frame <- data %>% filter(Language == input$language & acoustics == input$acoustic_parameter)
##plot, ADD audio file for points
hchart(data, "scatter", hcaes(x = Emotion , y = values, group = Vocalization)) %>%
hc_exporting(enabled = TRUE) %>%
hc_tooltip(crosshairs = TRUE, backgroundColor = "#FCFFC5",
shared = TRUE, borderWidth = 2) %>%
hc_title(text="Acoustic Parameter",align="center") %>%
hc_subtitle(text="Emotion - Vocalization Graph",align="center") %>%
hc_add_theme(hc_theme_elementary())
})
}
This is the codes for ui
##required packages.
library(shinydashboard)
require(shiny)
require(highcharter)
##there is two input, language: Dutch, Chinese, acoustic parameter: 10 different,
