is_point_in_path(x, y, poly) is_point_df_in_path(point_df, poly_df)
| x | The x coordinates of point. |
|---|---|
| y | The y coordinates of point. |
| poly | a list of numeric vectors defining the polygon list(c(x, y), c(x, y), ...) or a data.frame data.frame(x = c(0,0,1), y = c(0,1,1)) |
| point_df | a data.frame defining the points to check, column names are expected |
| poly_df | a data.frame defining a polygon, column are expected |
is_point_df_in_path: Find wether points are inside a polygon, defining
both as data frames with matching names
