Cleveland (1993) pointed out that the aspect-ratio is important in graphically showing the rate-of-change or shape information. For many time series, it is preferably to set this ratio to 0.25 than the default. In general, Cleveland (1993) shows that the best choice of aspect-ratio is often obtained by if the average apparent absolute slope in the graph is about 45 deg. But for many stationary time series, this would result in an aspect-ratio which would be too small. As a comprise we have chosen a default of 0.25 but the user can select other choices.

z |
ts object or vector, time series data |
SubLength |
maximum number of data points per panel. Default SubLength=Inf and regular graphics. For trellis graphics, set SubLength to a finite value. |
aspect |
optional setting for the aspect-ratio |
type |
plot type, default type="l" join points with lines |
xlab |
label for horizontal axis |
ylab |
optional label for vertical axis |
main |
optional title |

optional arguments passed to |
If z has attribute "title" containing a character string, this is used
on the plot.
Time series input using the function Readts
always
have this attribute set.
If SubLength
is finite, the lattice package is used and a graphic object of class trellis is produced.
Otherwise, the standard R graphics system is used and the plot is produced as a side-effect and there is no output.
