# s2sphere
The goal of s2sphere is to demo geographic operations in the s2 library
## Installation
```{r, eval=FALSE}
remotes::install_github("robinlovelace/s2sphere")
```
## In python
Here's how it works in Python
```{python}
import s2sphere
r = s2sphere.RegionCoverer()
p = s2sphere.LatLng(33, -122)
p
p1 = s2sphere.LatLng.from_degrees(33, -122)
p2 = s2sphere.LatLng.from_degrees(33.1, -122.1)
cell_ids = r.get_covering(s2sphere.LatLngRect.from_point_pair(p1, p2))
print(cell_ids)
```
## In R
Proof of concept to reproduce the above code using reticulate:
```{r}
library(s2sphere)
getCellIDs(33, -122, 33.1, -122.1)
```
```{r, echo=FALSE, eval=FALSE}
library(reticulate)
s2s = import("s2sphere")
latlng = s2s$LatLng(33, -122)
s2s
class(latlng)
s2sphere::LatLng(c(3, 9))
```
```{r lib, echo=FALSE}
# ## basic example code
# p1 = s2s$convert
# os <- import("os")
```
