使用现有问题的答案作为可重现代码的基础 here
我收到以下错误，不确定为什么它不起作用...这似乎是渲染时的一个普遍问题 hPlot在 shiny 中键入图表，因为我不断收到相同的错误

h1$series(data = c(NA, 4, 1, 3, 4), dashStyle = "shortdot")
h1$legend(symbolWidth = 80)
return(h1)
})
}))
下面是我在 rCharts 中升级后的 sessionInfo...这导致了同样的错误...另请注意，在 RStudio 的查看器中查看时，突出显示图表在本地工作，但在使用 showOutput 时不 Shiny 功能

最佳答案
在 showOutput() 中将 "Highcharts" 更改为 "highcharts" 为我修复了它(使用 rCharts 版本 0.4.5):
require(rCharts)
require(shiny)
runApp(list(
ui = pageWithSidebar(
headerPanel("rCharts: Highcharts"),
sidebarPanel(selectInput(
inputId = "x",
label = "Choose X",
choices = c('SepalLength', 'SepalWidth', 'PetalLength', 'PetalWidth'),
selected = "SepalLength"
)),
mainPanel(showOutput("myChart", "highcharts"))
),
server = function(input, output){
output$myChart <- renderChart2({
h1 <- Highcharts$new()
h1$chart(type = "spline")
h1$series(data = c(1, 3, 2, 4, 5), dashStyle = "longdash")
h1$series(data = c(NA, 4, 1, 3, 4), dashStyle = "shortdot")
h1$legend(symbolWidth = 80)
return(h1)
})
}
))
关于rCharts 突出显示 Shiny 的图表不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30335630/
