Suppose that I have geographic data about customers and stores and also in which store the customer made his last purchase. I want to plot customers and stores (according to their coordinates) and connect customers with their respective stores.
Here's a toy dataset:
library(tidyverse)
library(ggrepel)
customer.data <- data.frame(
customer = letters[1:12],
store = rep(paste0("S", 1:3), 4),
customer.lat = rnorm(12),
customer.lon = rnorm(12))
store.data <- data.frame(
customer = NA
store = paste0("S", 1:3),
store.lat = rnorm(3),
store.lon = rnorm(3)
)
data <- left_join(customer.data, store.data, by = "store") %>%
arrange(store, customer)
ggplot(data, aes(x = customer.lat, y = customer.lon, group = store)) +
geom_point(color = "blue") +
geom_point(aes(x = store.lat, y = store.lon), color = "red") +
geom_text_repel(aes(label = store))
So I want to do is to connect all customers of S1 store with its point using geom_line() or geom_segment() and so on. How can I do that?
ggplot(data, aes(x = customer.lat, y = customer.lon)) +
geom_point(aes(color = store)) +
geom_point(aes(x = store.lat, y = store.lon, color = store), size = 4) +
#geom_text_repel(aes(label = store)) +
geom_segment(aes(x = customer.lat, y = customer.lon,
xend = store.lat, yend = store.lon,
color = store))
