我构建了一个简单的闪亮应用。它在本地运行良好，但是当我将它加载到 Shinyapps.io 时出现错误。

错误信息如下：

警告：匿名错误：从连接读取错误

这是我的 ui.R 代码：

library(shiny)
library(dplyr)
library(ggplot2)
library(readr)
df <- read_csv("country_vaccinations.csv.zip")
countrIEs <- df %>% disTinct(country)

fluIDPage(
        titlePanel("CovID Vaccines by Country by Maria Freydlin"),h4("instructions:"),h5("Please SELEct a country from the dropdown List below to vIEw the timeline of @R_12_10586@l vaccines administered within the last few months."),a(href="https://github.com/mariafreydlin/shinyapp/tree/master",'link to UI and Server code files'),titlePanel("Vaccine Timeline by Country"),sIDebarLayout(
                sIDebarPanel(
                        SELEcTinput( "country","Country:",choices=countrIEs),hr()
                        
                ),mainPanel(
                        plotOutput("vaccinePlot")
                )
        )
)

这是我的 server.R 代码：

library(shiny)
library(dplyr)
library(ggplot2)
library(readr)
df <- read_csv("country_vaccinations.csv.zip")

function(input,output){
        df_@R_12_10586@l <- reactive({
                df %>%
                        filter(country==input$country)%>%
                        group_by(datE) %>%
                        summarise(@R_12_10586@l = sum(@R_12_10586@l_vaccinations,na.rm = T))
        })
        
        output$vaccinePlot <- renderPlot({
                ggplot(df_@R_12_10586@l(),aes(date,@R_12_10586@l)) + geom_line() +theme_bw()
        })
}

csv.zip 文件与 ui.R 和 server.R 位于同一文件夹中。

有什么想法、建议吗？

解决方法

file = unzip("country_vaccinations.csv.zip")
df <- read_csv(filE)
