【问题讨论】：
Reg_char 在ui 中有两个输入 - 也许您想使用不同的名称。此外，如果您可以尝试在您的问题中再次替换您的代码以清楚起见，这将有所帮助。
谢谢本。是这个问题，感谢您的帮助。
【参考方案1】：
请参阅下面的工作模型。我建议你看一些关于制作闪亮仪表板的教程 (https://shiny.rstudio.com/reference/shiny/latest/fluidPage.html)，因为你上面的代码在错误的地方有参数，你错过了实际调用仪表板的东西...shinyApp()
library(shiny)
library(shinydashboard)
ui <- fluidPage(
titlePanel("Zero Based Costing Model"),
sidebarLayout(
sidebarPanel(
"Enter client details",
numericInput("Chasis","Enter the original cost of chasis and cabin",100000),
numericInput("Reg_char","Enter the number of years after chasis and cabin making",0)
),
mainPanel(
tabsetPanel(type = "pills",
tabPanel("Body Chasis", value = 7, textOutput("MyChasis"), textOutput("MyReg_char")),
id = "tabselect"
)
)
)
)
server <- function(input, output)
output$MyChasis <- renderText(
paste("Original Cost of the Chasis is :", input$Chasis)
)
output$MyReg_char <- renderText(
if (as.numeric(input$Reg_char == 1) )
paste("The current cost of the vehicle with respect to number of years: ", as.numeric(input$Chasis * 0.9500))

【讨论】：
嗨@Kevin 我已经更新了代码，我只分享了有问题的部分以供快速参考，但我仍然无法在“body chasis”选项卡中获得所需的输出，请您查看完整的代码并帮助我。 请重新格式化您的问题，以便所有代码都包含在代码块中以上是关于用于计算的 R 中的 if else 语句的主要内容，如果未能解决你的问题，请参考以下文章
If_else 语句基于多个列，创建一个基于 R 中的真实语句数量平均的分数
R语言嵌套的ifelse语距：将一条If语句放在另一条If语句中，该语句作为嵌套的If else调用。If else语句允许我们根据表达式结果（TRUE或FALSE）打印不同的语句，执行不同的语句块
