Today is Valentine’s Day. And since both I and my sweetheart are `R` enthusiasts, here is how to say “I love you” using a statistical programming language:

``````library("dplyr")
library("gganimate")
library("ggplot2")

hrt_dat <- data.frame(t = seq(0, 2 * pi, by = 0.01)) %>%
bind_rows(data.frame(t = rep(max(.\$t), 300))) %>%
mutate(xhrt = 16 * sin(t) ^ 3,
yhrt = 13 * cos(t) - 5 * cos(2 * t) - 2 * cos(3 * t) - cos(4 * t),
frame = seq_along(t)) %>%
mutate(text = ifelse(frame > 300, "            J", "")) %>%
mutate(text = ifelse(frame > 500, "A           J", text)) %>%
mutate(text = ifelse(frame > 628, "A     +     J", text)) %>%
mutate(texty = 0, textx = 0)

ggplot(hrt_dat, aes(x = xhrt, y = yhrt)) +
geom_line(colour = "#C8152B") +
geom_polygon(fill = "#C8152B") +
geom_text(aes(x = textx, y = texty, label = text),
size = 18,
colour = "white",
vjust = "center") +
theme_void() +
