我有两个numericInput框,用于输入数字变量的最小值和最大值(范围)。我尝试使用splitLayout,该方法可以正常工作,但是当我为框添加标签时,框未对齐。
下面的代码
library(shiny)
# Define UI for application that draws a histogram
ui <- fluidPage(
# Application title
titlePanel("Old Faithful Geyser Data"),
# Sidebar with a slider input for number of bins
sidebarLayout(
sidebarPanel(
sliderInput("bins",
"Number of bins:",
min = 1,
max = 50,
value = 30)
),
# Show a plot of the generated distribution
mainPanel(
#fluidRow(
splitLayout(
variable <- faithful$waiting,
numericInput(paste("Min"),
#round = TRUE,
label = h5(c("test")),
min = round(min(variable, na.rm=TRUE)),
max = round(max(variable, na.rm=TRUE))-1,
value = round(min(variable, na.rm=TRUE))
), ## end slider input
numericInput(paste("Min"),
#round = TRUE,
label = h5(""),
min = round(min(variable, na.rm=TRUE))+1,
max = round(max(variable, na.rm=TRUE)),
value = round(max(variable, na.rm=TRUE))
)
)
)
))
# Define server logic required to draw a histogram
server <- function(input, output) {
output$distPlot <- renderPlot({
# generate bins based on input$bins from ui.R
x <- faithful[, 2]
bins <- seq(min(x), max(x), length.out = input$bins + 1)
# draw the histogram with the specified number of bins
hist(x, breaks = bins, col = 'darkgray', border = 'white')
})
}
# Run the application
shinyApp(ui = ui, server = server)
如果运行代码,您将看到框未对齐。
我该如何解决?

问题是您有一个框的标签,该标签将其向下推,而另一框没有等效的标签。要向下推第二个框,您需要包含一些内容,这些内容将被读为标签,但不显示任何内容。我使用HTML中断:
numericInput(paste("Min"),
#round = TRUE,
label = h5(HTML("<br/>")),
min = round(min(variable, na.rm=TRUE))+1,
max = round(max(variable, na.rm=TRUE)),
value = round(max(variable, na.rm=TRUE))
