Compute and plot level curves or level sets of a copula for COPinv
.
level.curvesCOP(cop=NULL, para=NULL, ploton=TRUE, lines=TRUE,
plotMW=FALSE, ramp=TRUE, delu=0.001, delt=0.10,
getlevel=NULL, silent=TRUE, ...)
Typically no values are returned because this function is used for its side effects, but the arguments can be such that the
list
.
A copula function;
Vector of parameters or other data structure, if needed, to pass to the copula;
A logical to toggle on the plot;
A logical to toggle calls to the lines()
function in R to draw the lines;
A logical to toggle to use the abline()
function in R to plot cross lines for the M
) and W
) copulas;
A logical to toggle whether the level curves are ramped in thickness according to the probability of the line;
The increment for
The increment delt=0.5
, then only the median plus the consequences of a defined getlevel
is used. If NULL
, then a sequence of getlevel
is used (if available);
If defined, then it is inserted into the sequence of levels getlevel
is returned in an R list
data structure. If more than one level is desired, then instead of repeated calls to this function, the joint.curvesCOP
function could be considered;
The argument of the same name given over to try()

operation on forming sequences of
Additional arguments to pass to the lines()
function in R.
