Render HTML on Shiny tabpanel - html

Question

The HTML output is created by summarytool::dfSummary function.
summarytools
summarytools uses Bootstrap’s stylesheets to generate standalone HTML documents that can be displayed in a Web Browser or in RStudio’s Viewer using the generic print() function.
When the HTML gets rendered on the tabpanel, the whole UI changes. Is there a way to render the HTML on the tabpanel without changing the UI?
library(summarytools)
ui <- fluidPage(
titlePanel("dfSummary"),
sidebarLayout(
sidebarPanel(
uiOutput("dfSummaryButton")
),
mainPanel(
tabsetPanel(
tabPanel("Data Input",
dataTableOutput("dataInput"),
br(),
verbatimTextOutput("profileSTR")),
tabPanel("dfSummary Output",
htmlOutput("profileSummary")))
)
)
)
server <- function(input, output, session) {
#Read in data file
recVal <- reactiveValues()
dfdata <- iris
#First 10 records of input file
output$dataInput <- renderDataTable(head(dfdata, n = 10), options = list(scrollY = '500px',
scrollX = TRUE, searching = FALSE, paging = FALSE, info = FALSE,
ordering = FALSE, columnDefs = list(list(className = 'dt-center',
targets = '_all'))))
#str() of input file
output$profileSTR <- renderPrint({
ProStr <- str(dfdata)
return(ProStr)
})
#Create dfSummary Button
output$dfSummaryButton <- renderUI({
actionButton("dfsummarybutton", "Create dfSummary")
})
### Apply dfSummary Buttom
observeEvent(input$dfsummarybutton, {
recVal$dfdata <- dfdata
})
#dfSummary data
output$profileSummary <- renderUI({
req(recVal$dfdata)
SumProfile <- print(dfSummary(recVal$dfdata), omit.headings = TRUE, method = 'render')
SumProfile
})
}
shinyApp(ui, server)

Version 0.8.3 of summarytools has a new boolean option, bootstrap.css which will prevent this from happening. Also, graph.magnif allows adjusting the graphs' size.
SumProfile <- print(dfSummary(recVal$dfdata),
method = 'render',
omit.headings = TRUE,
footnote = NA,
bootstrap.css = FALSE,
graph.magnif = 0.8)
The latest version can be installed with devtools:
devtools::install_github("dcomtois/summarytools")
Good luck :)
