# # PURPOSE:
|
|
# # Returns a list of vectors containing breaks and labels
|
|
# # for a continuous variable mapped to one of the axes for use with ggplot2
|
|
# # User enters:
|
|
# # - the range of the data
|
|
# # - the tick amount
|
|
# # - skip.steps (if any) = number of labels to skip
|
|
# # (i.e. show tick but no label)
|
|
# # e.g.
|
|
# # ggplotBreaks(c(0,150), tick =10, skip.steps = 1) # gives
|
|
# # $breaks
|
|
# # 0 10 20 30 40 50 60 70 80 90 100 110 120 130 140 150
|
|
# #
|
|
# # $labels
|
|
# # "0" " " "20" " " "40" " " "60" " " "80" " " "100" " " "120" " " "140" " "
