singletable
objectsProduces various plots for single table analysis.
## S3 method for class 'singletable' plot(x,type=type,file=NULL,select=c(1,2) ,xlab=NULL,ylab=NULL,addline=NULL,xlim=NULL,ylim=NULL,...)
x |
an object inheriting from class |
type |
a chracter string specifying the type of plots to
produce. Options are |
file |
a character string specifying the filename as which the plots are saved. Default is NULL to view on screen. See details. |
select |
a numeric value or vector specifying which distribution
should be plotted. |
xlab |
a character string specifying the x-axis label in the plot. Default is the name of the measure of association |
ylab |
a character string specifying the x-axis label in the plot. Default is "Density" |
addline |
a numeric value specifying the x-value for a vertical
reference line at |
xlim, ylim |
a numeric vectors of length 2 specifying the lower and upper limits of the axes |
... |
Other arguments can be passed to plot function |
If type="sidebyside"
, the posterior distribution of measure
and the prior distribution are drawn side by side in two plots. If
type="overlap"
, the posterior distribution of measure and
the prior distribution are overlaid in one plot.
If file=NULL
, the plots will be displayed on screen. Or
else, the plots will be saved as "./mmeta/codefile.pdf", where
"./" denotes current working directory.
