在 Shiny 中的 conditionalPanel 中添加多个条件

问题描述

我想知道是否可以在 conditionalPanel 中添加多个条件.这是一个例子:

I was wondering if it is possible to add more than one condition in conditionalPanel in shiny. This is an example:

 conditionalPanel(condition = "input.SELECT == 1",
                   #Slider 
                   sliderInput("D_FLAG", "Parameter X:",
                   min = 0.001, max = 3, value = 1.38, step = 0.1))

我想添加另一个条件(除了input.SELECT==1).我试过了，但没有用.

I want to add another condition (other than input.SELECT==1). I have tried this but it didn't work.

conditionalPanel(condition = c("input.SELECT == 1","input.FED==2"),
                   #Slider 
                   sliderInput("D_FLAG", "Parameter X:",
                   min = 0.001, max = 3, value = 1.38, step = 0.1))

但是没有用.如果有人能以正确的方式在上面的 conditionalPanel 中包含多个条件，我将不胜感激.

but it didn't work. I would appreciate if somebody could have some input on the right way for including multiple conditions in the conditionalPanel above.

推荐答案

只要语句最后的计算结果为 TRUE 或 FALSE，您就可以拥有任意复杂的语句.您可能希望将您的两个条件与 AND && 或 OR || 结合起来，就像这样(对于 OR):

You can have as complicated of a statement as you want as long as it evaluates to TRUE or FALSE at the end. You probably want to combine your two conditions either with AND && or OR ||, like this (for OR):

"input.SELECT == 1 || input.FED == 2"
