| draw.levset {denpro} | R Documentation |
Plots a level set of a piecewise constant 2D function.
draw.levset(pcf, lev=NULL, bary = NULL, propor = 0.1, col=NULL, bound = NULL, dendat = NULL, xaxt = "s", yaxt = "s", cex.axis = 1)
pcf |
piecewise constant function; output of "pcf.kern" or "pcf.func" |
lev |
real number; gives the level of the level set |
bary |
vector of 2 reals; the barycenter; if given will be plotted |
propor |
0<propor<1; the level set whose level is "propor" times the maximum value of the function will be drawn |
col |
the color of the lines of the plot; for example "red" |
bound |
vector of 4 real numbers; c(xmin,xmax,ymin,ymax); gives the values for the parameters "xlim" and "ylim" in the "plot" function; if "bound" is not specified, then the support of function "pcf" will be used |
dendat |
n*2-matrix or real values; when the "pcf" is a density estimate based on data "dendat", then specifying a value for the parameter "dendat", we can plot the data together with the estimate of a level set |
xaxt |
a character which specifies the x axis type; either "s" or "n"; see "par" |
yaxt |
a character which specifies the y axis type; either "s" or "n"; see "par" |
cex.axis |
the magnification to be used for axis annotation |
Makes a plot to the graphics window
