【问题描述】：
使用现有问题的答案作为可重现代码here的基础
我收到以下错误，但不确定为什么它不起作用...在将 hPlot 类型图表呈现为闪亮时，这似乎是一个普遍问题，因为我不断收到相同的错误

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)
})
}))
下面是我在 rCharts 中升级后的 sessionInfo...导致相同的错误...还请注意，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 函数时不闪亮

【问题讨论】：
-
试试
output$myChart <- renderChart({ h1 <- Highcharts$new() h1$set(dom = "myChart") }) -
还需要安装开发版的 rcharts install_github('rCharts', 'ramnathv',ref='dev')
-
删除并重新安装 rshiny 和 rcharts（您可能还需要重新安装其他依赖项）
