| plot.glmmfit {GLMMGibbs} | R Documentation |
Plot either the trace plots, the histograms,
or both, of the sampled values for parameters of
interest in a model fitted by glmm
plot.glmmfit(g, parameters, type = "b", hscale = "b", plots.per.page = 4, postscript)
g |
The result of a call to the glmm function,
an object of class glmmfit. |
parameters |
A vector of character strings giving names parameters in the model. If not missing, only sampled values for these parameters are plotted. If missing, sampled values for all parameters of interest are plotted. |
type |
A character, determining which type of
plot is given. If "t", "T", trace or
Trace a trace plot is made. If "h", "H",
"hist" or "Hist" a histogram is plotted.
If "b", "B", "both" or "Both" both
plots are made, side by side, with the trace plot on the
left and the histogrm on the right. Default is "b". |
hscale |
A character, determining the scale on which
scale sampled values of hyperparameter values are plotted.
If "t", "T", "tau" or "Tau" sampled
values are plotted on the tau scale. If "s", "S"
"sigma" or "Sigma" values are plotted on the
sigma scale. If "b", "B", "both" or
"Both", sampled values are plotted on both scales.
Default is "b". |
plots.per.page |
The number of variables plotted per page of output. Default is 4. |
postscript |
A character string. If it is not missing and
takes the value "file", say, the output is written
to files "file_page1.ps", "file_page2.ps", etc. |
The sampled values of some or all of the parameters of
interest in a model fitted
by the glmm function are plotted out. The parameters
for which values are plotted, whether trace plots, histograms,
or both are plotted, the scale on which hyperparameter values
are plotted, the number of variables plotted per page and
whether the plots are made to the screen or to postscript files
are all decided by the arguments to the function
