Empty "row-fluid" div at top and bottom of dataTableOutput - r

I have a shiny example using renderDataTable() to create an output.
I have removed all possible options (paging, filtering, searching, etc). However, there is now a blank row at the top and bottom of my table output, where the filtering and searching used to be.
How can I remove these two divs from inside the datatable wrapper, only when I have removed the filtering and searching options?
ui.R:
library(shiny)
shinyUI(pageWithSidebar(
headerPanel("dataTable Example"),
sidebarPanel(
"This is a sidebar"
),
mainPanel(
p("Check out the gaps below."),
wellPanel(
dataTableOutput('example1')),
p("No gaps here because of searching and paging."),
wellPanel(
dataTableOutput('example2')
)
)
)
)
server.R:
library(shiny)
shinyServer(function(input, output) {
x<-c(1,2,3,4,5)
y<-c('a','b','c','d','e')
test<-data.frame(x,y)
output$example1<-renderDataTable({test},options = list(iDisplayLength = 5,bSearchable = FALSE
,bFilter=FALSE,bPaginate=FALSE,bAutoWidth=TRUE
,bInfo=0,bSort=0))
output$example2<-renderDataTable({test})
})

You can use the sDom option see http://legacy.datatables.net/usage/options#sDom for more details:
library(shiny)
runApp(list( ui =pageWithSidebar(
headerPanel("dataTable Example"),
sidebarPanel(
"This is a sidebar"
),
mainPanel(
p("Check out the gaps below."),
wellPanel(
dataTableOutput('example1')),
p("No gaps here because of searching and paging."),
wellPanel(
dataTableOutput('example2')
)
)
)
, server = function(input, output) {
x<-c(1,2,3,4,5)
y<-c('a','b','c','d','e')
test<-data.frame(x,y)
output$example1<-renderDataTable({test},options = list(iDisplayLength = 5,bSearchable = FALSE
,bFilter=FALSE,bPaginate=FALSE,bAutoWidth=TRUE
,bInfo=0,bSort=0
, "sDom" = "rt"
))
output$example2<-renderDataTable({test})
}
)
)

Horizontal scrolling in editableDTUI and editableDT in shiny dashboard

i need to give flexibility to app user so that they can edit/modify a table . I am using the below codes
UI code:
tabItem(tabName = "manual_override",
fluidRow(
editableDTUI("table1")
Server Codes:
callModule(editableDT,"table1",data=reactive(bigtable),inputwidth=reactive(100))
but the problem is that bigtable has more than 15 columns to display and the horizontal scroll is not appearing
I have tried the same with library(DT) with 20 col.
If that solves your problem.
ui.r
library(shiny)
library(DT)
shinyUI(
fluidPage(
navbarPage("Big file upload + Horizental Scrolling",
tabPanel("Data Import",
fluidRow(
fileInput("file","Upload Your CSV",multiple = FALSE),
column(6,
div(style = 'overflow-x: scroll', DT::dataTableOutput('csv_data')))
)
)
)
)
)
server.r
library(shiny)
shinyServer(function(input, output) {
csv_data_fun<-eventReactive(input$file,{
df<-read.csv(input$file$datapath,
header =TRUE)
return(df)
})
output$csv_data<-DT::renderDataTable({
DT::datatable(csv_data_fun(),rownames = FALSE)%>%formatStyle(columns=colnames(csv_data_fun()),background = 'white',color='black')
})
})
output Screen
Please check whether you want this
I have done with editDT, But this time with default mtcars dataset.
Added the code in UI part
div(style = 'overflow-x: scroll',editableDTUI("table1"))
New Code
library(shiny)
library(editData)
if (interactive()) {
ui <- fluidPage(
textInput("mydata","Enter data name",value="mtcars"),
column(6,
div(style = 'overflow-x: scroll',editableDTUI("table1")
)
)
)
server <- function(input, output) {
df=callModule(editableDT,"table1",dataname=reactive(input$mydata),inputwidth=reactive(170))
output$test=renderPrint({
str(df())
})
}
shinyApp(ui, server)
}
Please check this time if this solves your problem. You can tweak the things to change according to your requirements.
Please accept the answer if solves your issue.

Text input in Shiny is not working when switching from MainPanel to Tabset views

I have a Shiny App that takes a text input and shows it on the main panel (I used this answer to build it):
ui.r:
library(shiny)
shinyUI(fluidPage(
titlePanel("This is a test"),
sidebarLayout(
sidebarPanel(
textInput("text1", "Enter the text", ""),
actionButton("goButton", "Go")
),
mainPanel(
h3(textOutput("text1", container = span))
)
)
)
)
server.r:
shinyServer(function(input, output) {
cap <- eventReactive(input$goButton, {
input$text1
})
output$text1 <- renderText({
cap()
})
})
It worked great until I decided to add a Tabset panel, and show the input on one of the tabs. I modified mainPanel() in ui.r as:
mainPanel(
tabsetPanel(type = "tabs",
tabPanel("t1"),
tabPanel("t2",
tabPanel("t3"), h3(textOutput("text1", container = span)),
)
)
After this change, I am getting an error when launching an app:
ERROR: cannot coerce type 'closure' to vector of type 'character'
Is there something I am missing?
You have to put the content within the tab within the call to tabPanel. Ex:
mainPanel(
tabsetPanel(
type = "tabs",
tabPanel("t1"),
tabPanel("t2"),
tabPanel("t3", h3(textOutput("text1", container = span)))
)
)
Thus, server.R is unchanged from you question, and ui.R becomes:
library(shiny)
shinyUI(
fluidPage(
titlePanel("This is a test"),
sidebarLayout(
sidebarPanel(
textInput("text1", "Enter the text", ""),
actionButton("goButton", "Go")
),
mainPanel(
tabsetPanel(
type = "tabs",
tabPanel("t1"),
tabPanel("t2"),
tabPanel("t3", h3(textOutput("text1", container = span)))
)
)
)
)
)

Centering a plot within a fluidRow in Shiny

I have a fluidRow with a plot rendered in one of the columns. I would like to know how to center the plot when I have manually specified the plot width via the renderPlot({create plot here}, width = ##) function (thus, it doesn't take up the full width of the column).
ui.R code:
setwd("C:/Users/Nate/Documents/R Working Directory/appFolder/example")
shinyUI(fluidPage(
titlePanel("Test"),
sidebarLayout(
sidebarPanel(
p('stuff here')
),
mainPanel(
tabsetPanel(id = 'tabs1',
tabPanel("main",
fluidRow(
column(8,
plotOutput('plot1')),
column(4,
p('2nd column'))),
fluidRow(
p("2nd row of viewing area"))
),
tabPanel("second",
p("main viewing area")),
tabPanel("third",
p('main viewing area')
)
))
)
))
server.R code:
shinyServer(function(input, output, session) {
output$text1 = renderText({
paste("text output")
})
output$plot1 = renderPlot({
x = runif(10,0,10)
y = rnorm(10)
plot(x,y)
}, width = 300)
})
align="center" can be included within the column expression (not within plotOutput though).
e.g.
fluidRow(
column(8, align="center",
plotOutput('plot1')
)
)
You could use align="center" as part of your plotOutput() function. So your ui.R would like this:
ui.R
setwd("C:/Users/Nate/Documents/R Working Directory/appFolder/example")
shinyUI(fluidPage(
titlePanel("Test"),
sidebarLayout(
sidebarPanel(
p('stuff here')
),
mainPanel(
tabsetPanel(id = 'tabs1',
tabPanel("main",
fluidRow(
column(8,
plotOutput('plot1',align="center")),
column(4,
p('2nd column'))),
fluidRow(
p("2nd row of viewing area"))
),
tabPanel("second",
p("main viewing area")),
tabPanel("third",
p('main viewing area')
)
))
)
))

Can I have multiple submit buttons in R shiny?

In my R shiny application, I would like to have one button to submit one set of inputs (which affect one portion of the output) and another one to submit the remaining inputs (which affect a different portion of the output). The code in the widgets example of the Shiny tutorial uses a submitButton but it seems like all the inputs are delivered when that single button is pressed? Thanks in advance for your help.
Here is an example showing actionButtons controlling reactive components:
library(shiny)
runApp(list(
ui = fluidPage(
titlePanel("Hello Shiny!"),
sidebarLayout(
sidebarPanel(
tags$form(
numericInput('n', 'Number of obs', 100)
, br()
, actionButton("button1", "Action 1")
)
, tags$form(
textInput("text", "enter some text", value= "some text")
, br()
, actionButton("button2", "Action 2")
)
),
mainPanel(
plotOutput('plot')
, textOutput("stext")
)
)
),
server = function(input, output) {
output$plot <- renderPlot({
input$button1
hist(runif(isolate(input$n)))
})
output$stext <- renderText({
input$button2
isolate(input$text )
})
}
)
)
