在闪亮的应用程序中创建一个带有国旗的 multi.sj 闪亮的小部件
Create a multi.sj shiny widget with country flags in shiny app
我正在尝试创建一个像这样 multi.js 闪亮的小部件 here。但是我想念 flags
对象。有人知道我在哪里可以找到并加载它吗?
library(shiny)
library(shinyWidgets)
countries<-c("Belgium","Greece","Brazil")
ui <- fluidPage(
multiInput(
inputId = "Id010",
label = "Countries :",
choices = NULL,
choiceNames = lapply(seq_along(countries),
function(i) tagList(tags$img(src = flags[i],
width = 20,
height = 15), countries[i])),
choiceValues = countries
)
)
server <- function(input, output) {
}
shinyApp(ui, server)
根据 chrome 的开发工具,shinyWidgets 画廊中的图像似乎是从如下网址提取的:https://cdn.rawgit.com/lipis/flag-icon-css/master/flags/4x3/de.svg.
如果您想将其包含在输入小部件中,您需要定义一个包含相应 url 的字符向量
countries <- c('de', 'at', 'br')
img_urls <- paste0(
'https://cdn.rawgit.com/lipis/flag-icon-css/master/flags/4x3/',
countries, '.svg'
)
input_widget <- multiInput(
inputId = "Id010",
label = "Countries :",
choices = NULL,
choiceNames = lapply(
seq_along(countries),
function(i) {
tagList(
tags$img(src = img_urls[i], width = 20, height = 15),
countries[i]
)
}
),
choiceValues = countries
)
然后您可以将输入小部件放在您身体的任何位置UI
shinyApp(fluidPage(input_widget), function(...) {})
