ds %>% kable(row.names=FALSE, digits=0, booktabs=TRUE)| Location | MinTemp | MaxTemp | Rainfall | Evaporation |
|---|---|---|---|---|
| Williamtown | 12 | 17 | 20 | 1 |
| SydneyAirport | 14 | 18 | 8 | 2 |
| MelbourneAirport | 21 | 34 | 0 | 14 |
| Canberra | 16 | 26 | 7 | NA |
| Richmond | 2 | 20 | 0 | NA |
