r - shinydashboardPlusGallery() 示例不起作用

Question

我已经按照演示部分中官方 GitHub 页面上的说明安装了 R 包 shinydashboardPlus:https://github.com/RinteRface/shinydashboardPlus

按照指示，我安装并加载了包以及包依赖项。然后尝试在 R Studio 中使用命令 >shinydashboardPlusGallery() 运行shinydashboardPlus的演示仪表板，但失败并给出了错误。

然后我超越并安装并加载了几个软件包只是为了确定，但它仍然不起作用。

下面是我的代码:

install.packages("pacman")
# List all the packages to be used below.
pacman::p_load(shiny, shinydashboard, shinydashboardPlus, styler, shinyAce, shinyWidgets, shinyjqui, shinyEffects)

library(shiny)
library(shinydashboard)
library(shinydashboardPlus)
shinydashboardPlusGallery()

我收到的错误如下:

我使用的是 Windows 11 操作系统。我的R和R Studio版本如下:

我真的很想使用shinydashboardPlus包来构建我的仪表板，但似乎无法开始使用它。

我在尝试访问图书馆的演示库时遇到了同样的问题。这显然是 shinydashboard 和 shinydashboardPlus 包之间的命名空间问题。如果执行以下行search():

> search()
 [1] ".GlobalEnv"                 "package:shinyEffects"       "package:styler"            
 [4] "package:shinyAce"           "package:shinyWidgets"       "package:shinydashboard"    
 [7] "package:shinyjqui"          "package:shiny"              "package:shinydashboardPlus"
[10] "tools:rstudio"              "package:stats"              "package:graphics"          
[13] "package:grDevices"          "package:utils"              "package:datasets"          
[16] "package:methods"            "Autoloads"                  "org:r-lib"                 
[19] "package:base" 

如您所见，在我的例子中，shinydashboard 包放置在 shinydashboardPlus 包之前，因此 dashboardPage 函数是使用的是属于 shinydashboard 包而不是 shinydashboardPlus 包的包。

这是一个错误，我的快速解决方案是:

• 找到演示应用程序所在的位置，您应该在类似于 ~\Documents\R\R-4.1.2\library\shinydashboardPlus\examples 的路径中找到它。
• 打开global.R 文件。
• 您必须更改顺序以确保shinydashboardPlus 包在 shinydashboard 包之后调用。

例如:

# Load packages
library(shiny)
library(shinyjqui)
library(shinyWidgets)
library(shinyAce)
library(styler)
library(shinyEffects)
library(shinydashboard)
library(shinydashboardPlus)
