I have a dataset that have the long and lat information, as well as the 'Experiment' info for each long and lat.
I used addCircleMarkers to add markers. And I want to have popup options for each marker. I tried to call "Experiment" at popup, but it gives me errors that it can't find this variable. I am not sure where it went wrong.
Dataset
ui <- fluidPage(
titlePanel("Land Explorer"),
selectInput("year", "Year of G2F", choices = c("2014", "2015", "2016", "All")),
fluidRow(
mainPanel(
tags$style(type = "text/css", "#map {height: calc(100vh - 80px) !important;}"),
leafletOutput("map"), width = "100%", height = 1000)
)
)
server <- function(input, output){
pal <- colorFactor("RdYlGn", county_simplified$zone, reverse = T, na.color = "white")
state_popup <- paste0("<strong>State: </strong>",
county_simplified$region,
"<br><strong>County: </strong>",
county_simplified$subregion)
g2f <- reactive ({
if (input$year == "2014"){
g2f_latlong = g2f_latlong[g2f_latlong$year == 2014, ]
}
else if (input$year == "2015"){
g2f_latlong = g2f_latlong[g2f_latlong$year == 2015, ]
}
else if (input$year == "2016") {
g2f_latlong = g2f_latlong[g2f_latlong$year == 2016, ]
}
else if (input$year == "All"){
g2f_latlong = g2f_latlong
}
else (g2f_latlong = g2f_latlong)
})
output$map <- renderLeaflet({
leaflet() %>%
addTiles() %>%
addPolygons(data = county_simplified, weight = 1,
color = "white",
dashArray = '3',
fillOpacity = 0.7,
fillColor = ~pal(zone),

The dataset is not reproducible and unclear. It is hard to do get data from an image. Instead you could provide the output ofdput(head(g2f_latlong))which is more easy to work.

You are not returning the filtered data from reactive environment, so your addCircleMarkers function do not get data to plot on leaflet. Change your reactive environment as shown below and i hope this solves your issue.
g2f <- reactive({
if (input$year == "2014") {
filtered_data <- g2f_latlong[g2f_latlong$year == 2014, ]
}else if (input$year == "2015") {
filtered_data <- g2f_latlong[g2f_latlong$year == 2015, ]
}else if (input$year == "2016") {
filtered_data <- g2f_latlong[g2f_latlong$year == 2016, ]
}else if (input$year == "All") {
filtered_data <- g2f_latlong
}else {filtered_data <- g2f_latlong}
return(filtered_data)
})

With the limited explanation and data i could only check foraddCircleMarkers. But you are using ` county_simplified` &state_boundrydata, which are not available to check foraddPolygons.
