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择的输入以用作 ggplotgeom_col()交互参数中的参数。
我的目的是根据所选值更改交互图，checkboxGroup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 input$cekgr_fill 中的至少 2 个参数构建交互条形图，例如：'fill=interaction(JENIS,TH_ADA, sep="*") '。
'get(input$cekgr_fill)' 只传递第一个参数，即：JENIS，并忽略 TH_ADA。
你能帮帮我吗？谢谢你。
这是我的代码：
shinyUI(dashboardPage(
#Nama Dashboard
dashboardHeader(title = "OPERASIONAL"),
dashboardSidebar(
checkboxGroupInput("cekgr_gudang", label = h4("Gudang"),
choiceNames = list("Karanganyar","Binong",
"Rancaudik","Tanjungrasa",
"Ciwangi"),
choiceValues = list("Karanganyar","Binong",
"Rancaudik","Tanjungrasa",
"Ciwangi")
),
checkboxGroupInput("cekgr_komoditas", label = h4("Komoditas"),
choices = c("Beras","Minyak Goreng",
"Terigu","Gula","Gabah", "Ketan")
),
checkboxGroupInput("cekgr_tahun","Tahun",
choices = c("2018","2019","2020","2021")
),
checkboxGroupInput("cekgr_opsional", label = h4("Opsional"),

),
checkboxGroupInput("cekgr_fill", label = h4("Fill Grafik"),
