我是Shiny和Shinydashboard的新手。请考虑以下代码片段(巨大代码的一小部分):
dbsidebar <- dashboardSidebar(
sidebarMenu(
menuItem("Dashboard", tabName = "dashboard", icon = icon("dashboard")),
menuItem("Rank List", icon = icon("th"), tabName = "Widgets1", badgeColor = "green"),
menuItem("Build Your", icon = icon("th"), tabName = "Widgets2", badgeColor = "green"),
menuItem("Groups", icon = icon("th"), tabName = "Widgets3", badgeColor = "green")
)
)
dbBody <- dashboardBody(
tabItems(
tabItem(tabName = "dashboard",
fluidRow(
#Pie Charts
splitLayout(
#cellWidths = c("50%", "50%"),
style = "border: 1px solid silver;",
cellWidths = 450,
cellArgs = list(style = "padding: 6px"),
plotlyOutput("Piechart1", width = "400px", height = "200px"),
plotlyOutput("Piechart2", width = "400px", height = "200px"),
plotlyOutput("Piechart3", width = "400px", height = "200px")
)
)
),
tabItem(tabName = "Widgets1",
#Sidebar with a slider input for number of bins
sidebarLayout(
sidebarPanel(
sliderInput("TCScore","TCScore:",min = 0, max = 100, value = c(0,100))
),
# Show a plot of the generated distribution
mainPanel(
tabPanel("Heading", plotlyOutput("tbTable"))
)
),
downloadButton('downloadData', 'Download')
),
tabItem(tabName = "Widgets2", "XX"
# #Data Table
# sidebarLayout(
# sidebarPanel(
# sliderInput("TCCScore","TCCScore:",min = 0, max = 100, value = c(0,100)),
# ),
#
# # Show a plot of the generated distribution
# mainPanel(
# tabPanel("Heading", dataTableOutput("tbTable1"))
# )
#
# ),
# downloadButton('downloadData', 'Download')
),
tabItem(tabName = "Widgets3", "third"
)
)
)
在仪表板侧栏上,我添加了4个选项卡-仪表板,Widget1,Widget2,Widget3。最初,对于每个选项卡,我都使用简单的文本来呈现UIdashboardBody并正确显示。我开始填写这些部分中的每一个-“ dashboard”,“ Widget1”,显示对我来说都是正确的。不幸的是,对于“ Widget2-当我删除“ XX”并取消注释上面显示的代码时,UI完全失真。看起来仪表板中的主要UI元素未呈现?有人可以告诉我我做错了什么吗? ?请帮忙,对不起,我还没有发布完整的工作代码,但是它太长了,因此我只需要提供一个小代码段即可。
提前谢谢!欢呼!
