library(move)

data("move_data", "basemap_data")
m <- align_move(move_data, res = 4, unit = "mins")

# create spatial frames using a custom NDVI base layer
r_list <- basemap_data[[1]]

# add a progress bar:

frames.a[[100]]

# or in red and larger
frames.b <- add_progress(frames, colour = "red", size = 2.5)
frames.b[[100]]
