### Setup

```{r setup, message=FALSE}
library(sf)
library(dplyr)
library(ggplot2)
```

## Task 1 - Clean and Merge Data

### Parking Violation Data

```{r}
nyc = readRDS("/data/nyc_parking/nyc_parking_2014_cleaned.rds")

head(nyc)
```

### Geocoding Data

```{r warning=FALSE}
pluto = read_sf("/data/nyc_parking/pluto_manhattan/MNMapPLUTO.shp")

head(pluto$Address)

plot(st_geometry(pluto))
```

### Clean data

```{r}
nyc_ticket = nyc %>%
  filter(violation_precinct >= 1, violation_precinct <= 34) %>%
  transmute(
    violation_precinct = violation_precinct,
    address = paste(house_number, street_name) %>% tolower()  
  )
```


```{r}
pluto_xy = pluto %>% 
  st_centroid() %>% 
  transmute(address = Address %>% tolower()) %>%
  cbind(., st_coordinates(.)) %>%
  as_tibble() %>%
  select(-geometry)

plot(select(pluto_xy, -address), pch=16, cex=0.1)
```


### Merge data

```{r}
match = inner_join(
  pluto_xy,
  nyc_ticket,
  by = "address"
)
```

```{r}
ggplot(match, aes(x=X, y=Y, color=as.factor(violation_precinct))) +
  geom_point()
```

## Task 2 - Modeling

### Setup

```{r}
