我对新手有点陌生,我一直在尝试制作一个交互式地图,显示一年内(2019年5月开始,2020年5月结束)为一个项目收集的注册表数量。
当我运行代码时,弹出窗口将打开并按我的意愿显示地图和滑块输入框,但是地图未显示数据,当我单击每种状态时,它将显示NA。
运行代码时,出现以下错误消息:
“ ==”不兼容的方法(“ Ops.factor”,“ Ops.yearmon”),“ ==“不兼容的方法(“ Ops.factor”,“ ==。Date”) “ ==“不兼容的方法(” Ops.factor“,” ==。Date“)的” ==“不兼容的方法(” Ops.factor“,” = = .Date“)用于==”不兼容的方法(“ Ops.factor”,“ ==。Date”)对于“ ==”不兼容方法(“ Ops.factor”,“ ==。Date”) =“
这是我的代码:
ui <- bootstrapPage(
# Application title
titlePanel("Numero de registros"),
tags$style(type = "text/css", "html, body {width:100%;height:100%}"),
leafletOutput("map", width = "100%", height = "100%"),
absolutePanel(top = 10, right = 10,
sliderInput("range", "Fecha",
min = as.Date(as.yearmon("2019-05-23")),
max = as.Date(as.yearmon("2020-05-07")), # most recent date on the CSV file. UPDATE with each CSV
value = as.Date(as.yearmon("2019-05-23")),
timeFormat = "%b %Y",
)
)
)
# Shiny app - server
server <- function(input, output, session) {
# Reactive expression for the data subsetted to what the user selected
filteredData <- reactive({
states <- left_join(states, subset(reg, reg_date == input$range[1]),
by = "id")
states
})
# This reactive expression represents the palette function, which changes as the user makes selections in UI.
colorpal <- reactive({
colorFactor(palette = c("#D8F0C6", "#AED68F", "#8ABA64", "#66993E", "#477622", "#274C0A"), reg$Freq)
})
output$map <- renderLeaflet({
# Use leaflet() here, and only include aspects of the map that won't need to change dynamically
states <- left_join(states, subset(reg, reg_date == as.yearmon("2019-05-23")), by = "id")
pal <- colorpal()
leaflet(states) %>% addTiles() %>%
setView(-102, 23.8, 5)%>%
addLegend(position = "bottomright",
pal = pal, values = ~reg$Freq,
title = "Registros") %>%
addTiles()
})
# Incremental changes to the map (in this case, replacing the circles when a new color is chosen) should be performed in an observer. Each independent set of things that can change should be managed in its own observer.
observe({
pal <- colorpal()
leafletProxy("map", data = filteredData()) %>%
clearShapes() %>%
addPolygons(stroke = TRUE, weight = 1, color = "#000000",
fillOpacity = 0.8, smoothFactor = 0.5,
fillColor = ~pal(Freq),
popup = ~ sprintf("Estado: %s<br/>Registros: %s",
stri_trans_totitle(state_name),
round(Freq, 1)))
})
}
shinyApp(ui, server)
我真的很感激有人可以帮助我修复代码。
