使用闪亮时,如何传递 checkboxGroup 的选定输入值以用作 geom_col() 的 ggplot2 交互中的参数?

How to pass chosen input values of checkboxGroup to be used as an argument in ggplot2 interaction of geom_col() when using shiny?

我正在使用 Shiny 构建一个简单的仪表板以用于我的工作。一切都很好,直到我发现我无法传递选定的输入以用作 ggplot geom_col() 交互参数中的参数。

我的目的是根据 checkboxGroup 的所选值更改交互图,其中所选值将用作 ggplot 中 fill=interaction(....) 的参数。

我在这个阶段遇到了问题:

ggplot(data= opsdata2, aes(x=reorder(GUDANG,KUANTUM/1000), y=KUANTUM/1000, 
                                   fill=interaction(get(input$cekgr_fill),sep = "*")
               ))

'get(input$cekgr_fill)' 仅传递第一个参数,而我的目的是使用输入 $cekgr_fill 中的至少 2 个参数构建交互条形图,例如: 'fill=interaction(JENIS,TH_ADA, sep="*")'.

'get(input$cekgr_fill)'只传递第一个参数,即:JENIS,而忽略TH_ADA。

你能帮帮我吗?谢谢。

这是我的代码:

您需要select 适当的交互变量。我使用了 pickerInput 到 select 最多 5 个变量进行交互。如果 selected 少于 2 个变量,则会打印一条消息。也许有一种更优雅的方法可以做到这一点。现在,我已经提供了一个快速的答案。请试试这个
