hi: I think I have finally reached some tough(er) graphics questions,
so help would be appreciated.
* In an ordinary log xy plot, I have two lines
lines( poslowess( x1, y1, f=0.11 ) );
lines( poslowess( x1, y2, f=0.11 ) );
y1 and "y2" are actually a "best" and "worst" scenario. So, I am
wondering whether it is tough/easy to shade the area between the two lines.
* I have a historical rate of stock return series (yes, I teach
finance). I would like to make a ts plot on the left
(plot(date,returns,type="h")), and a plot(density(returns)) on the
right. works nicely with par(mfrow=c(1,2)), but it would be even nicer
if I could rotate the density plot 90 degrees, so that it is more
apparent that the density plot is an aggregation of the points at the
same y coordinates. (if need be, a histogram could replace the density
plot.) Is it possible to rotate an entire figure. the "horizontal"
parameter to ps.options is not an option for plot afaik.
* on an easier question, I got beat: how do I make the tickmarks appear
*inside* the graph, and shrink the distance between the tick text and
the tick axis?
help appreciated. apologies for imposing on everyone's time.
regards, /iaw
