Use

library(ggplot2)
library(ggflags)

set.seed(1234)
d <- data.frame(
  x = rnorm(50), y = rnorm(50),
  country = sample(c("ar", "fr", "nz", "gb", "es", "ca", "lv", "qa"), 50, TRUE),
  stringsAsFactors = FALSE
)

ggplot(d, aes(x = x, y = y, country = country, size = x)) +
  geom_flag() +
  scale_country() +
  scale_size(range = c(0, 15))
