I was able to find the geom_curve control points in ggplot using the answer on this question:

I am now wondering how to apply this same function to geom_line to obtain all the control points along the geom_line I created on my ggplot.

`b$data[[1]]`

gives the **starting** and **ending** points and

`p$layers[[1]]$geom_params`

gives the curve information (angle, curvature, ...).

But how do I find all the coordinates/points along the geom_line so I can reproduce the line with those points?

```
C <- ggplot() +
geom_sf(data = world, fill = "grey69", size = 0.1, colour = "transparent") +
scale_x_continuous(limits = c(-180, 180), breaks = seq(-180, 180, by = 40)) +
scale_y_continuous(limits = c(-90, 90), breaks = seq(-90, 90, by = 30)) +
coord_sf(expand = FALSE) +
labs(x = "Longitude", y = "Latitude") +
geom_sf(data = world, color = "grey87", fill = "grey87", size = 0.1) +
geom_line(aes(c(19, 6),c(-32,-40)),
lineend = "round", size = 0.4, col = "gray20", linetype = "solid", alpha = 0.6)
```
