I have points made in different months and different years. And here's what I get:
ggplot() +
geom_point(
data = reka.coord,
colour = "black",
shape = 20,
size = 5,
aes(X, Y, group = biotop)
) +
theme_bw() +
theme(axis.text.x = element_blank(),
axis.text.y = element_blank(),
axis.title.x = element_blank(),
axis.title.y = element_blank(),
axis.ticks = element_blank(),
legend.position = "none"
) +
facet_grid(year ~ month) +
theme(strip.text = element_text(size = 20, colour = "black"))
Here's what I want:
fascet_wrap
I tried too:
