Examples

library(moveVis)
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]]
r_times <- basemap_data[[2]]

# \donttest{
frames <- frames_spatial(m, r_list = r_list, r_times = r_times, r_type = "gradient",
                         fade_raster = TRUE)

# add a progress bar:
frames.a <- add_progress(frames)
frames.a[[100]]

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