  colors = NULL,
  shapes = NULL,
  point_size = 1,
  polygon_color = "#2C3E50",
  title = "Grid Comparison"
)

Arguments

...	Named data frames with longitude and latitude columns
polygons	Optional sf object to show polygon boundaries

Value

ggplot object

Examples

grid <- expand.grid(longitude = seq(72.5, 77.5, by = 1), latitude = seq(18.5, 21.5, by = 1))
grid$temperature <- seq_len(nrow(grid))
cells <- sf::st_make_grid(sf::st_as_sfc(sf::st_bbox(
  c(xmin = 72, ymin = 18, xmax = 78, ymax = 22),
  crs = 4326
)), n = c(2, 1))
polys <- sf::st_sf(region = c("west", "east"), geometry = cells)
coarse <- grid[grid$longitude < 75, ]
compare_grids(fine = grid, coarse = coarse, polygons = polys)
