Question

我遇到错误问题：

参数＆＃34; mainPanel＆＃34;缺少，没有默认

我有类似问题的搜索论坛，但我是初学者，所以一些微不足道的错误可能是错误的。

主屏幕也不缺少，逗号是正确的。你有什么建议吗？

使用此链接可以使用csv文件： https://ufile.io/wknza

请参阅代码：

library(shiny)
library(fmsb)
library(ggplot2)

nba2 = read.csv("headerlivingconditionsPos.csv", header = TRUE, sep = ",")
nba = read.csv("livingconditions.csv", header = TRUE, sep = ",")
header = read.csv("headerlivingconditions.csv", header = TRUE, sep = ",")

nbaSelectAttributes = nba2
nbaSelectAttributes$COUNTRIES <- NULL
nbaSelectAttributes$TEAM <- NULL
nba2$X <- NULL
attributes <- attributes(nbaSelectAttributes)$names
countriesName = attributes(nba$COUNTRIES)$levels
teams = attributes(nba$TEAM)$levels

提前感谢您的帮助！

错过括号以关闭你的ui中的ui <- fluidPage( titlePanel("NBA Analysis Application"), navlistPanel( "Menu", tabPanel("COUNTRIES Comparison", sidebarLayout( sidebarPanel( selectInput("country1", "Choose the first country:", choices = countriesName), selectInput("country2", "Choose the second contry:", choices = countriesName), column(12, checkboxGroupInput("checkGroup", h3("Choose the stats that you want to compare (at least 3):"), choices = list("Housing" = "HOUSING", "Income" = "INCOME", "Jobs" = "JOBS", "Community" = "COMMUNITY", "Education" = "EDUCATION", "Environment" = "ENVIRONMENT", "Civic Engagement " = "CIVIC ENGAGEMENT", "Health " = "HEALTH ", "Life satisfaction" = "LIFE SATISFACTION", "Safety" = "SAFETY", "Work Life Balance" = "WORK LIFE BALANCE", selected = "JOBS")) ) ), mainPanel( plotOutput("radarChart"), p("Every variable is measured in scale of 0 to 10.") ) ) ), tabPanel("Info", fluidRow( shiny::column(6, offset = 0, h1("Probando")) ) ) ) )。修改后的UI代码如下：

.bind()

参数＆＃34; mainPanel＆＃34;缺少，没有默认值
