闪亮的Flexdasboard反应式压力计未更新
问题描述 投票：1回答：1
我已在我的Shinyapp中添加了一个反应计。量表应显示与运动员先前所有时间的最低和最高值相比最近的跳跃高度得分。
selectInput被设置为Athlete和最近的日期(max(jumpdata$Date))。我的代码对于无功仪表的最大值非常有效，但不会在无功更新最小值。当我运行该应用程序时，最小值将显示第一个运动员的输入，然后在我更新并选择其他输入（但最大更改）时保持在相同的值。
我不确定障碍物在哪里，因为最大值正在更新。

根据发布在github上的解决方法，这是我的新代码，但无法渲染。我不确定基于我的原始量表要包含什么作为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renderUI和debounce解决此问题（延迟渲染，以使计算准备就绪。）>
请注意，我已更改范围逻辑以实际显示一些颜色并查看以下内容：

force rerendering gaugeOutput("Gauge_JH") }) g <- reactive({ t <- jumpdata %>% select(Date, Athlete, JumpHeight_cm) %>% filter(Athlete == input$Athlete) f <- t %>% filter(Date == max(Date)) minJump = min(t$JumpHeight_cm) maxJump = max(t$JumpHeight_cm) diffJump = maxJump-minJump gauge( value = f$JumpHeight_cm, min = min(t$JumpHeight_cm), max = max(t$JumpHeight_cm), sectors = gaugeSectors( 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) ), symbol = 'cm' ) }) } shinyApp(ui, server)
但是，在所有这些不便之处，我都会切换图书馆。这是一种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", delta = list(reference = meanJump), gauge = list( bar = list(color = currentJumpColor), axis = list(range = list(minJump, maxJump)), 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 }) } shinyApp(ui, server)
