   For time series plots using zoo I want the layout to be horizontal
rectangles rather than squares. When I specify par(pin = c(5,2.5)) nothing
happens; the plot frame is square regardless of specifying pin within the
plot command or prior to issuing the plot command. My reading of plotting docs
does not show me what I'm doing incorrectly.

   An example of the command I use is:

plot(s95.z$Se, pin = c(6,2) , main = "Selenium", xlab = "Date", ylab = "Concentration")

   A pointer to what I'm missing is needed.
