闪亮的 Flexdasboard 反应式仪表未更新

Shiny Flexdasboard Reactive Gauge not Updating

我在我的 shinyapp 中添加了反应量表。该仪表将显示最近的跳跃高度得分与运动员之前所有时间的最小值和最大值的比较。

select输入设置为 Athlete 和最近的日期 (max(jumpdata$Date))。我的代码非常适用于最大反应式仪表,但不会为最小值进行反应式更新。当我 运行 应用程序时,第一个运动员的输入显示最小值,然后在我更新和 select 不同的输入时保持相同的值(但最大变化)。

我不确定障碍在哪里,因为最大值正在更新。

根据 github 上发布的解决方法,这是我的新代码,但我无法渲染它。根据我原来的标准,我不确定要包含什么作为 input$range

ui.r

library(shiny)
library(shinydashboard)
library(flexdashboard)
library(dplyr)

jumpdata <- read.csv("SO CMJ Dummy.csv")
jumpdata$Date <- as.Date(jumpdata$Date, "%Y-%m-%d")

shinyUI(
    fluidPage(
        sidebarPanel(width = 3,
                     selectInput("Athlete", label = "Athlete",
                                 choices = unique(jumpdata$Athlete))),
        mainPanel(
            fluidRow(
                box(title = "Jump Height", gaugeOutput("Gauge_JH")),
                uiOutput("Gauge_JH_Proxy")
            ))
    ))

server.r

library(shiny)
library(shinydashboard)
library(flexdashboard)
library(dplyr)

jumpdata <- read.csv("SO CMJ Dummy.csv")
jumpdata$Date <- as.Date(jumpdata$Date, "%Y-%m-%d")

shinyServer(function(input, output){
    output$Gauge_JH <- renderGauge({
        f <- jumpdata %>%
            select(Date, Athlete, JumpHeight_cm) %>%
            filter(Athlete == input$Athlete & Date == c(max(jumpdata$Date)))

        t <- jumpdata %>%
            select(Date, Athlete, JumpHeight_cm) %>%
            filter(Athlete == input$Athlete)

        g <- gauge(f$JumpHeight_cm, min = min(t$JumpHeight_cm), max = max(t$JumpHeight_cm), symbol = 'cm', gaugeSectors(
            success = c((max(t$JumpHeight_cm)*.9), max(t$JumpHeight_cm)), warning = c((max(t$JumpHeight_cm)*.8), max(t$JumpHeight_cm)*.9), danger = c(min(t$JumpHeight_cm), max(t$JumpHeight_cm)*.8)
        ))
        print(g)
    })
    output$Gauge_JH_Proxy <- renderUI({

        input$Athlete # force re-rendering
        gaugeOutput(outputId = "Gauge_JH", width = "30%", height = "200px")
    }) 

})

可以通过使用 renderUIdebounce(延迟渲染,以便计算准备就绪)来解决此问题。

请注意,我已经更改了范围逻辑以实际显示一些颜色并查看以下内容:

但是,由于所有这些不便,我会切换图书馆。 这是一个 plotly 方法:

library(shiny)
library(shinydashboard)
library(dplyr)
library(plotly)

# jumpdata <- [copy & paste jumpdata here]
jumpdata$Date <- as.Date(jumpdata$Date, "%Y-%m-%d")

ui <- fluidPage(
  fluidPage(
    sidebarPanel(width = 3,
                 selectInput("Athlete", label = "Athlete",
                             choices = unique(jumpdata$Athlete))),
    mainPanel(
      fluidRow(
        plotlyOutput("Gauge_JH_plotly", height = 250, width = "50%")
      ))
))

server <- function(input, output, session) {

    output$Gauge_JH_plotly <- renderPlotly({

      t <- jumpdata %>%
        select(Date, Athlete, JumpHeight_cm) %>%
        filter(Athlete == input$Athlete)

      f <- t %>% filter(Date == max(Date))

      currentJump = f$JumpHeight_cm
      meanJump = mean(t$JumpHeight_cm)
      minJump = min(t$JumpHeight_cm)
      maxJump = max(t$JumpHeight_cm)
      diffJump = maxJump-minJump

      success = c(min(t$JumpHeight_cm) + diffJump * 0.8, max(t$JumpHeight_cm))
      warning = c(min(t$JumpHeight_cm) + diffJump * 0.4, min(t$JumpHeight_cm) + diffJump * 0.8)
      danger = c(min(t$JumpHeight_cm), min(t$JumpHeight_cm) + diffJump * 0.4)

      ranges <- unique(c(danger, warning, success))

      currentJumpColor <- c("red", "orange", "green")[findInterval(currentJump, ranges, rightmost.closed = TRUE)]

      fig <- plot_ly(
        domain = list(x = c(0, 1), y = c(0, 1)),
        value = currentJump,
        title = list(text = "Jump Height [cm]"),
        type = "indicator",
        mode = "gauge+number+delta",

          steps = list(
            list(range = danger, color = "lightgray"),
            list(range = warning, color = "gray")),
          threshold = list(
            line = list(color = "green", width = 4),
            thickness = 0.75,
            value = maxJump))) 
      fig <- fig %>% layout(margin = list(l=30, r=30, t=80, b=30))

      fig
    })
