问题描述
我有一个列为 TRUE
或 FALSE
值
data(mtcars)
mtcars $ Favorite< - FALSE
我有兴趣将此列(收藏夹)显示为有光泽的复选框。
runApp(list(
ui = basicPage(
h2('the mtcars data'),
dataTableOutput('mytable')
),
server = function(input,output){
输出$ mytable = renderDataTable({
mtcars
})
}
))

I have a column with TRUE
or FALSE
values
data("mtcars")
mtcars$Favorite <- "FALSE"
I am interested in displaying this column (Favorite) as a checkbox on shiny.
runApp(list(
ui = basicPage(
h2('The mtcars data'),
dataTableOutput('mytable')
),
server = function(input, output) {
output$mytable = renderDataTable({
mtcars
})
}
))

Not sure how to make it work, any help is much appreciated.
Is this what you're looking for?
library(shiny)
library(DT) # dev from github
runApp(list(
ui = basicPage(
h2('The mtcars data'),
DT::dataTableOutput('mytable'),
h2("Selected"),
tableOutput("checked")
),
server = function(input, output) {
# helper function for making checkbox
shinyInput = function(FUN, len, id, ...) {
inputs = character(len)
for (i in seq_len(len)) {
inputs[i] = as.character(FUN(paste0(id, i), label = NULL, ...))
}
inputs
}
# datatable with checkbox
output$mytable = DT::renderDataTable({
data.frame(mtcars,Favorite=shinyInput(checkboxInput,nrow(mtcars),"cbox_"))
}, server = FALSE, escape = FALSE, options = list(
paging=FALSE,
preDrawCallback = JS('function() {
Shiny.unbindAll(this.api().table().node()); }'),
drawCallback = JS('function() {
Shiny.bindAll(this.api().table().node()); } ')
) )
# helper function for reading checkbox
shinyValue = function(id, len) {
unlist(lapply(seq_len(len), function(i) {
value = input[[paste0(id, i)]]
if (is.null(value)) NA else value
}))
}
# output read checkboxes
output$checked <- renderTable({
data.frame(selected=shinyValue("cbox_",nrow(mtcars)))
})
}
))
