我正在使用有序列表显示结果。现在我想在数字上添加一个圆圈，颜色从绿色变为红色。使用是第一个结果是优先级，其他跟随的较少。所以颜色渐变从绿色变为红色。

library("shiny")
library("shinyWidgets")
ui <- fluidPage(
column(
width = 4,

inputId = "id", label = "Choices :",
choices = c("Banana", "Blueberry", "Cherry", "Coconut", "Grapefruit",
"Kiwi", "Lemon", "Lime", "Mango", "Orange", "Papaya"),

`count-selected-text` = "{0}/{1} fruits"),
multiple = TRUE
)
)

output$res <- renderPrint({
input$id
})
}

我有一个闪亮的应用程序，其中一项功能是允许用户编辑表中的值，当单击运行时，它将使用用户输入作为函数的值，然后更新同一个表中的结果。下面是当前表和预期表的示例。因此，在第一个表中，如果用户更改通道 A 和 C 的电流值并单击运行，它应该将自身更新为表预期输出中反映的值。
所以我的问题是，是否可以将可编辑的 DT 值作为函数的输入。
library(shiny)
library(DT)
shinyApp(
ui = fluidPage(
DT::dataTableOutput("x1"),
actionButton("opt_run", "Run"),
tags$h1("Expected Output"),
DT::dataTableOutput("x2")
),
server = function(input, output, session) {
df <- data.table(Channel = c("A", "B","C"),
Current = c("2000", "3000","4000"),
Modified = c("2500", "3500","3000"),
New_Membership = c("450", "650","700"))
output$x1 = renderDT(df, selection = 'none', editable = TRUE)
expdf <- data.table(Channel = c("A", "B","C"),
Current = c("3000", "3000","5000"),
Modified = c("3500", "3500","6000"),
New_Membership = c("650", "650","1100"))
output$x2 = renderDT(expdf, selection = 'none', …我正在尝试为收入范围中断创建直方图，并在每次中断时进行计数。我从基本直方图 bl.ocks 中挑选了一个例子。下面是这个代码。我如何生成直方图以在 x 轴上显示收入范围并以 y 为单位。
