# Themes

Install and load the [`hrbrthemes` package](https://hrbrmstr.github.io/hrbrthemes/index.html). It's a package that provides some great default themes. 

It's not available on CRAN, where we normally install packages from, which means you have to install it slightly differently. You'll use the `devtools` package and then use this to install the `hrbrthemes` package. Use the code below.

```{r}
# install.packages("devtools")
# devtools::install_github("hrbrmstr/hrbrthemes")
library(hrbrthemes)
```

Then add the `theme_ipsum` to your plot.

```{r}
ggplot(data = sleep_by_gender, 
       mapping = aes(x = gender, 
                     y = avg_sleep,
                     fill = gender)) +
  geom_col(show.legend = FALSE) +
  geom_text(aes(label = round(avg_sleep, 1)),
            vjust = 1.5,
            color = "white") +
  scale_fill_brewer(palette = "Dark2",
                    na.value = "blue") +
  scale_y_continuous(limits = c(0, 8),
                     breaks = c(0, 1, 2, 3, 4, 5, 6, 7, 8)) +
  labs(title = "Women sleep slightly more than men on average",
       y = "Hours of sleep per night",
       x = "") +
  theme_ipsum()
```
