我正在尝试将交互式热图部署为闪亮的应用程序,但不仅仅是交互式热图,而是闪亮热图的精美热图,但是当我运行 deployapp 时没有任何反应

这是我的用户界面

library(shiny)
library(heatmaply)
library(shinyHeatmaply)
data(mtcars)
shinyUI(fluidPage(
    titlePanel("Interactive heatmap"),
    fluidRow(plotlyOutput("heatmap"))
))

这是我的服务器

library(shiny)
library(heatmaply)
library(shinyHeatmaply)
data(mtcars)
shinyServer(function(input,output) {
    output$heatmap <- if(interactive()){
data(mtcars)
launch_heatmaply(mtcars)
}

    })

通过运行

rsconnect::deployApp("/Users/temporal.UOS-12599/Desktop/New folder") 

DONE

但最后什么都没有发生

这是要在部署的应用程序中显示的数据

请问有什么帮助吗?

您需要将数据传递给obj. 这是一个基于 heatmaplyGadget代码的示例:

library(shiny)
library(htmltools)
library(DT)
library(heatmaply)
library(dplyr)
library(datasets)

sample_013 <- data.frame(stringsAsFactors=FALSE,
                         NANA = c("ABCB1", "ACVR1B", "ACVR2A", "APC", "ARID1A", "ARID1B"),
                         NADriver = c(1, 1, 1, 1, 1, 1),
                         NAsnv_t_013 = c(0, 0, 0, 1, 0, 1),
                         NAsnv_o_013 = c(1, 0, 0, 1, 0, 1),
                         NAindel_t_013 = c(0, 0, 0, 0, 1, 1),
                         NAindel_o_013 = c(0, 0, 0, 0, 1, 1),
                         NADeleted_ot_013 = c(0, 0, 0, 0, 1, 1),
                         NADeleted_o_013 = c(0, 0, 0, 0, 0, 1))

plotHeight <- 800
obj <- list(sample_013 = sample_013, iris = iris)

if (!"list" %in% class(obj)) 
  obj = list(obj)

保存到文件app.R以下也应该工作

library(shinyHeatmaply)

sample_013 <- data.frame(stringsAsFactors=FALSE,
                         NANA = c("ABCB1", "ACVR1B", "ACVR2A", "APC", "ARID1A", "ARID1B"),
                         NADriver = c(1, 1, 1, 1, 1, 1),
                         NAsnv_t_013 = c(0, 0, 0, 1, 0, 1),
                         NAsnv_o_013 = c(1, 0, 0, 1, 0, 1),
                         NAindel_t_013 = c(0, 0, 0, 0, 1, 1),
                         NAindel_o_013 = c(0, 0, 0, 0, 1, 1),
                         NADeleted_ot_013 = c(0, 0, 0, 0, 1, 1),
                         NADeleted_o_013 = c(0, 0, 0, 0, 0, 1))

shinyHeatmaply::launch_heatmaply(sample_013,viewerType = 'browserViewer')

运行文件夹 rsconnect::deployApp("/Users/temporal.UOS-12599/Desktop/New folder")

应该拿起该文件并运行应用程序。
