[R] About plot graphs

[Stephen Liu]

Hi Greg,

Thanks for your advice.

I'm not prepared altering the shape of the graphs to be plotted.  What I'm 
trying to do is to pop up a rectangle layout window with following command.

The command;
layout(matrix(1:2, nrow=1))

pop up a square window.  What I need is a rectangular window for the graphs to 
be plotted.  Otherwise the graphs are squeezed changing shape.

I looked at ?layout but can't resolve how to make it.  Can you help?  TIA

B.R.
Stephen L

There is a graphical parameter that controls whether a plot is square or takes 
up the maximum amount of room (rectangle), see ?par and look at the entry for 
pty. 


It is possible that you set pty='s' or it may be that the plot method sets it, 
without us knowing what type of object Date and Test01$Date are we don't know 
which method is creating your plot and cannot be much more help (that is meant 
as a subtle hint to provide the information requested in the footer of every 
post and the posting guide).

Some methods may set pty='s' as default but have an option to change it.
