A Shiny input binding wrapper for the histoslider React component.
Install the stable release of histoslider on CRAN:
install.packages("histoslider")input_histoslider() currently supports creating
histogram sliders from numeric, date, datetime vectors. The histogram
bins may be customized through the breaks argument of an
implicit call to hist().
library(shiny)
library(histoslider)
numerics <- rnorm(100)
dates <- sample(
seq(as.Date('2020-01-01'), as.Date('2030-01-01'), by = "1 month"),
size = 500, replace = TRUE
)
datetimes <- sample(
seq(as.POSIXct('2020-01-01 00:01'), as.POSIXct('2030-01-01 00:01'), by = "1 month"),
size = 500, replace = TRUE
)
ui <- bslib::page_fixed(
input_histoslider("numeric", "Numeric", numerics, start = -1, end = 1),
input_histoslider("date", "Date", dates, breaks = 15),
input_histoslider("datetime", "Date Time", datetimes),
verbatimTextOutput("values")
)
server <- function(input, output) {
output$values <- renderPrint({
str(list(
numeric = input$numeric,
date = input$date,
datetime = input$datetime
))
})
}
shinyApp(ui, server)
An input_histoslider() can also be updated
programmatically via update_histoslider(). For example
usage, see the inst/examples
folder.
