I am able to embed checkbox in each cell of a DT column from reading this post.
Imagine I have a dataframe with a logical column named "value" containing some TRUE values, and I want the checkbox in "value_check" column to appear as checked for those that are TRUE upon app start, like shown below: How would I do so?
library(shiny)
library(DT)
df <- data.frame(item = c("a", "b", "c"), value = c(TRUE, NA, NA))
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
}
## obtaining checkbox value
shinyValue = function(id, len) {
unlist(lapply(seq_len(len), function(i) {
value = input[[paste0(id, i)]]
if (is.null(value)) FALSE else value
}))
}
server <- function(input, output, session) {
output$tbl <- renderDT(server = FALSE, escape = FALSE, editable = TRUE, options = list(
dom = 't', paging = FALSE, ordering = FALSE,
preDrawCallback = JS('function() { Shiny.unbindAll(this.api().table().node()); }'),
drawCallback = JS('function() { Shiny.bindAll(this.api().table().node()); } ')
), {
df$value_check <- shinyInput(checkboxInput, nrow(df), "check")
df
}
)
}
ui <- fluidPage(
DTOutput("tbl")
)
shinyApp(ui, server)
