I am using S+ 6.2 (Build 6713) under Win 2K on an IBM laptop (500MB)
I am trying to "pretty up" some graphics, by adding annotation within the plot
frame. When using par("usr") to get the coordinates of the plot frame I
sometimes get an erroneous value for par("usr")[3], the y coordinate of the
lower x-axis of the plot.
This seems to relate to when I plot only part of the data for an ecdf, but not
a cumulative probability plot. However, within my ecdf function I do not call
plot until after I have selected the subset of data to be plotted, The lower
x-axis plots at a y-coordinate of about 0.1, just as I expect, but
par("usr")[3] returns a value of 0.03, which is what I would expect for the
total data. So I am bemused and befuddled.
Has this behaviour ever been seen before, or what is the stupid mistake I am
making?
Any help would be appreciated,
