Convenient interface for plotting density estimates.
dens( x , adj=0.5 , norm.comp=FALSE , main="" , show.HPDI=FALSE , show.zero=FALSE , rm.na=TRUE , add=FALSE , ...)Vector of values to construct density from, or data frame. If x is a data frame, then dens plots a grid of densities, one for each column in x.
width of density kernal.
If TRUE, overlays normal density comparison.
If a numeric value, displays HPDI of same width. For example, show.HPDI=0.95 shows a 95 percent HPDI inside the density.
If TRUE, draws a vertical line at location of zero on horizonal axis.
If TRUE, removes NAs before computing density
If TRUE, overlays density on an existing plot
Other parameters to pass to density, which constructs the density estimates.
This function merely provides a convenient interface for plotting density estimates produced by density. It handles both single vectors and multiple vectors, contained within a data frame.
Highest Posterior Density Intervals (HPDI) are calculated by HPDinterval in the coda package.
