Problem with merging my data with the map and visualise the maximum.

[LindoDolph]

incidents_per_suburb <- q6 %>%
group_by(Suburb) %>%
summarise(total_incidents = sum(Count)) %>%
arrange(desc(total_incidents))

merged_data <- cross_join(incidents_per_suburb, map)

suburb_most_incidents <- merged_data[which.max(merged_data$total_incidents), "Suburb"]

head(merged_data)

suburb_most_incidents <- merged_data[which.max(merged_data$total_incidents), "Suburb"]

Map1 <- ggplot(merged_data, aes(x= long, y= lat, group==group)) +
geom_polygon(aes(fill = "#69b3a2", color = "white")) +
geom_text(data = merged_data, aes(label = ifelse(Suburb == suburb_most_incidents, Suburb, "")),
size = 3, color = "black", check_overlap = TRUE) +
theme_void() +
coord_map() +
labs(title = "Incidents per Suburb")

Map1

Hi, it is difficult to work out what is going on without a reproducible example - difficult for spatial data too, though you could create an aspatial example. Does suburb_most_incidents look like what you're after? You could probably add that to merged_data with an if_else() and avoid the at whole section.

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
