[R] ggplot aestetics: beginner question - I am lost in endless possibilites

[Hadley Wickham]

You are going to find your life much easier if you:

* Organise your code so it's easier to read
* Use a consistent naming scheme for your variables
* Learn a bit more about how to modify variables succintly

Here's my rewriting of your script to make it easier to see what's going on.

library(tidyverse)

df <- tibble(
  name = c("Ernie","Ernie","Ernie", "Leon","Leon","Leon"),
  recorded_time = c("03.01.2011","04.01.2011","05.01.2011",
"04.01.2011","05.01.2011","06.01.2011"),
  known_state = c("breeding","moulting","moulting", "breeding","breeding",NA)
)
df$recorded_time <- lubridate::dmy(df$recorded_time)

ggplot(df) +
  geom_tile(
    aes(recorded_time, name, fill = known_state),
    colour = "black",
    height = 0.5
  ) +
  scale_fill_discrete(na.value = "white")
