tmap_mode("view") # doesn't affect plot mode
## make some points
grid <- sf::st_make_grid(what = "centers")
## with <500 points, maps correctly
tm_shape(grid[1:499]) +
tm_symbols(fill = "blue", col = "blue", shape = 4)
## with 500 points or more, the symbols revert to default circles, ignoring the shape parameter
tm_shape(grid[1:500]) +
tm_symbols(fill = "blue", col = "blue", shape = 4)
