[R] About plot graphs

[Greg Snow]

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.
