我有几个关于 R 闪亮仪表板的问题。
用户界面
library(shinydashboard)
library(shiny)
dashboardPage(
dashboardHeader(title = 'Test Interface'),
dashboardSidebar(width = 600,
h3('-------Input Data-------'),
fluidRow(
column(6, div(style = "height:10px"), fileInput(inputId = 'FileInput', label = 'Upload Input:', accept = c('csv','tsv','txt'))),
column(2, div(style = "height:3px"), checkboxInput(inputId = 'header', label = 'Header', value = FALSE)),
column(2, div(style = "height:12px"), radioButtons(inputId = 'sep', label = 'Separator', choices = c(comma=',',tab="\t",space=' '), selected = ","),offset = 1)
),
fluidRow(column(6, div(style = "height:1px"), fileInput(inputId = 'FileInput1', label = 'Upload Second Input:'))),
br(),
h3('-------Select Foreground-------'),
fluidRow(
column(5, div(style = "height:17px"), radioButtons(inputId = 'cutoff', label = 'Selection', choices = c('Up'='pos','Down'='neg','Both'='both'))),
br(),
column(3, div(style = "height:1px"), textInput(inputId = 'fc', label = "Fold Change", value = '0')),
column(3, div(style = "height:1px; margin-left:10cm"), height = 6,textInput(inputId = 'pvalue', label = "Adj. Pvalue",value = '0.05'))
),
fluidRow(column(2, h1(" "), actionButton(inputId = 'select', label = "Select Data"))),
fluidRow(column(5, div(style = "height:25px;font-color:blue"), downloadButton('download', 'Download Plot')))),
dashboardBody(
tabsetPanel(type="tabs", id = "tabvalue",
tabPanel(title = "Input Table", value = 'tab1', DT::dataTableOutput('table')),
tabPanel(title = "Plot", value = 'tab7', plotOutput('plot',width = 800,height = 800)))))
服务器.R
library(shiny)
shinyServer(function(input, output, session){
})
我不知道如何将垂直滚动条添加到dashboardSidebar。在我的实际应用程序中,当我运行应用程序时,最后一个元素是不可见的。
谢谢!
