当我在笔记本电脑上运行我的Shiny应用程序时出现此错误。 在我用库（git2r）添加一行代码之前，应用程序工作正常。 在我的代码下面。
有人可以帮忙吗？感谢。
ui.R
league_desc <- c("Premier League","Serie A","Bundesliga","La Liga")
shinyUI(
fluidPage(
headerPanel(h1('Football Statistics', align = "center"),
h2('Data on the 4 main european football leagues. Period 2011 - 2015', align = "center")),
sidebarPanel(
h4('Selection Parameters', align = "center"),
这是我的ui.R文件的初始部分。 请注意我正在使用fluidPage命令，即使我没有应用特定的格式化选项（我没有“www”文件夹或“bootstrap.css”文件）。
library(devtools)
library(git2r)
library(shiny)
library(rCharts)
library(dplyr)
library(rjson)
library(rNVD3)
league_desc <- c("Premier League","Serie A","Bundesliga","La Liga")
shinyUI(
fluidPage(
headerPanel(h1('Football Statistics', align = "center"),
h2('Data on the 4 main european football leagues. Period 2011 - 2015', align = "center")),
sidebarPanel(
h4('Selection Parameters', align = "center"),
radioButtons("League_RB",
"Select League",
league_desc,
selected = "Premier League",
inline = FALSE,
width = NULL),
radioButtons("Year_RB",
"Select Season",
c(2011:2015),
selected = 2011,
inline = FALSE,
width = NULL),
sliderInput("matchdays",
"Matchdays:",
min = 1,
max = 38,
value = c(1, 38))
),
mainPanel(
tabsetPanel(
tabPanel(p(icon("line-chart"), "Charts"),
h4('Standings', align = "center"),
showOutput("chart1"),
h4('Shots & Goals', align = "center"),
showOutput("chart2"),
h4('Relationship Shots vs Goals', align = "center"),

tabPanel(p(icon("table"), "Full Data"),
dataTableOutput("dataTable")),
tabPanel(p(icon("cogs"), "Regression"),
h4('Predict Number of Goals based on Number of Shots on Target', align = "left"),
numericInput("sot","1) Expected Number of Shots on Target",value=0,min=0),
radioButtons("League_Pred_RB",

答案 0 :(得分：3)
两个包具有相同功能的问题。
在tag我shiny中取消屏蔽功能unloadNamespace("shiny")并在所有包require(shiny)
运作良好。如果您需要标记而不是闪亮使用::
library(devtools)
library(git2r)
unloadNamespace("shiny")
library(shiny)
library(rCharts)
library(dplyr)
library(rjson)
library(rNVD3)
league_desc <- c("Premier League","Serie A","Bundesliga","La Liga")

sidebarPanel( h4('Selection Parameters', align = "center"),
radioButtons("League_RB", "Select League", league_desc, selected = "Premier League", inline = FALSE, width = NULL),
radioButtons("Year_RB", "Select Season", c(2011:2015), selected = 2011, inline = FALSE, width = NULL),
sliderInput("matchdays", "Matchdays:", min = 1, max = 38, value = c(1, 38)) ),
mainPanel( tabsetPanel(
tabPanel(p(icon("line-chart"), "Charts"),

tabPanel(p(icon("table"), "Full Data"), dataTableOutput("dataTable")),
