问题描述
我希望我的Shiny应用程序的用户使用行名和列名填写2x2表的值。当然,我可以使用4个输入框来完成此操作,但是我认为将所有内容整齐地放置会很棘手。尽管如此,我还是希望使用一种表格布局,例如 DT
包提供的布局。因此,我的问题是:是否可以由用户填充数据表
(或类似的东西)?
I want users of my Shiny app to fill in the values of a 2x2 table with row and column names. Of course, I could do it with 4 input boxes, but I assume that it will be tricky to position everything neatly. Despite that, I would prefer a table layout such as the one provided by the DT
package. Thus, my question is: Is it possible to have a datatable
(or something similar) filled by the user?
推荐答案
使用 DT
的解决方案:
library(DT)
library(shiny)
dat <- data.frame(
V1 = c(as.character(numericInput("x11", "", 0)), as.character(numericInput("x21", "", 0))),
V2 = c(as.character(numericInput("x21", "", 0)), as.character(numericInput("x22", "", 0)))
)
ui <- fluidPage(
fluidRow(
column(5, DT::dataTableOutput('my_table')),
column(2),
column(5, verbatimTextOutput("test"))
)
)
server <- function(input, output, session) {
output$my_table <- DT::renderDataTable(
dat, selection = "none",
options = list(searching = FALSE, paging=FALSE, ordering=FALSE, dom="t"),
server = FALSE, escape = FALSE, rownames= FALSE, colnames=c("", ""),
callback = JS("table.rows().every(function(i, tab, row) {
var $this = $(this.node());
$this.attr('id', this.data()[0]);
$this.addClass('shiny-input-container');
});
Shiny.unbindAll(table.table().node());
Shiny.bindAll(table.table().node());")
)
output$test <- renderText({
as.character(input$x11)
})
}
shinyApp(ui, server)
