Hello, ron,

have you looked at the help page of qqplot and consequently tried, e.g., 
the following?

xy <- qqplot( rt(300, df = 5), rt(300, df = 5),
               xlim = c(-10, 10), ylim = c(0, 10))
str( xy)

For example I want to define that, x-axis range will be -10 to 10 and y-axis range will be 0-10 (just an example on what I am looking for). Additionally I want to get the entire list of (x,y) coordinates for all plotted points.
