| Trace {Umacs} | R Documentation |
Generates an object including the information necessary to show a trace plot of a scalar parameter in a Umacs sampling function.
The sampler is built using the Umacs function Sampler;
this function is only to be used within the Sampler function call.
Trace(name, label = name, ylim = NULL)
name |
Name of the scalar parameter to be traced, e.g. "code{theta[1]}". |
label |
Label to be shown in the trace plot window. By default the same as code{name}. |
ylim |
Range of the vertical axis. By default, the range is extended as necessary to display the highs and the lows of the trace. |
If ylim is not specified (if it is NULL), the range of the vertical
axis is adjusted automatically.
Trace is to be used only within the Sampler function call.
An object of class Trace,
to be further processed by the Umacs function Sampler.
