# Research question

What I care about…

# Load data

I want to analyze stuff. There's data about democracy online. Let's load it.

```{r load-libraries-and-data, message=FALSE, warning=FALSE}
library(tidyverse)

democracy <- read_csv("https://moderndive.com/data/dem_score.csv")
```


# Wrangle data

I want to see which country changed the most

```{r calculate-change}
change_in_score <- democracy %>% 
  mutate(change = `1992` - `1952`) %>% 
  select(country, change) %>% 
  mutate(change_absolute = abs(change)) %>% 
  arrange(desc(change_absolute))

change_in_score
```

I want it to be tidy

```{r tidify-data}
tidy_democracy <- democracy %>% 
  gather(year, score, -country) %>% 
  mutate(year = parse_number(year))
tidy_democracy
```


# Do stuff with data

## Myanmar

I want to look at Myanmar

```{r myanmar-graph}
myanmar_only <- tidy_democracy %>% 
  filter(country == "Myanmar")

ggplot(data = myanmar_only, 
       mapping = aes(x = year, y = score)) +
  geom_line() +
  geom_hline(yintercept = -5, color = "red") + 
  geom_hline(yintercept = 5, color = "blue")
```

## Lithuania

Lithuantiua's turn

```{r lith-graph}
lith_only <- tidy_democracy %>% 
  filter(country == "Lithuania")

ggplot(data = lith_only, 
       mapping = aes(x = year, y = score)) +
  geom_line() +
  geom_hline(yintercept = -5, color = "red") + 
  geom_hline(yintercept = 5, color = "blue")
```


All coutnries

```{r graph-all-countries}
ggplot(tidy_democracy, aes(x = year, y = score, group = country)) + 
  geom_line(alpha = 0.1) +
  geom_hline(yintercept = -5, color = "red") + 
  geom_hline(yintercept = 5, color = "blue")
```
