There are several options for plotting bicop_dist objects. The density of a bivariate copula density can be visualized as surface/perspective or contour plot. Optionally, the density can be coupled with standard normal margins (default for contour plots).
bicop_dist object.
plot type; either "surface" or "contour".
options are: "unif" for the original copula density,
"norm" for the transformed density with standard normal margins,
"exp" with standard exponential margins, and "flexp" with
flipped exponential margins. Default is "norm" for type =
"contour", and "unif" for type = "surface".
integer; the plot is based on values on a size x size grid,
default is 100.
optional arguments passed to contour or
wireframe.

## construct bicop_dist object for a student t copula
obj <- bicop_dist(family = "t", rotation = 0, parameters = c(0.7, 4))
## plots
plot(obj) # surface plot of copula density
contour(obj) # contour plot with standard normal margins
contour(obj, margins = "unif") # contour plot of copula density
