There are some things to take from there and some others not to take.

• "fixed" : our default breaks
• pretty /sd : pretty is nice but it just creates breaks, so can be used with i = pretty(x) with default what , sd is apparently pretty used on centered/scaled data, so same thing
• "equal" is a better name than "n_interval", we should use it as an alias and throw away n_interval after some time
• "quantile" : we have it, but should add examples of different quantiles distribution using the functions directly in breaks
• "kmeans", "hclust", "bclust", "fisher", or "jenks" : clustering algorithms, some are in base some will require some research, maybe inspect code from classInt (check liscence)

close this task when those issues are assigned as their own issues
