我想进行反应显示,根据输入选择器的哪个值选择显示不同数量的绘图.在mtcars数据集的情况下,假设我想让用户选择在Nr之间切割.Gears或Nr.Carcarratos为要生产的地块.
看着 unique(mtcars$gear)我们看到它有4 3 53个可能的值,同时unique(mtcars$carb)有4 1 2 3 6 86个可能的值.因此,我想在Nr. of Carburators选择时生成6个单独的图,并且在选择时仅绘制3个图Nr. of Gears.我曾经玩过,conditionalPanel但是我在选择器之间切换一次或两次之后总是会爆炸.救命?

selectInput(inputId = "choosevar",
label = "Choose Cut Variable:",
choices = c("Nr. of Gears"="gear",
"Nr. of Carburators"="carb")),
htmlOutput('mydisplay') ##Obviously I'll want more than one of these...
# conditionalPanel(...)
))
