Subject: identifying what labels have been created in a plot
Colleagues
R 2.8.0; OS X, Vista, Ubuntu Linux
In some instances, when I create a graphic using plot(XVAR, YVAR), it
would be valuable to know the values that R will display on the y-axis
(e.g., if the range of data is 0-70, it might display 0, 10, 30, 50,
70). Is there a simple means to access these values?
Also, in some instances, additional ticks appear between the displayed
values (in this case, at 20, 40, 60). Can I obtain the list of the
positions of all ticks?
Access to this information permits me to tailor the ticks and labels
in a particular manner.
Thanks for any suggestions.
Dennis
