scatter.enfa {adehabitat} | R Documentation |
Performs the scatter diagrams of objects of class enfa
.
scatter.enfa(x, xax = 1, yax = 2, h, pts = FALSE, ncont = 1, clabel = 1, colZ = "blue", colS = "orange", lwdZ = 2, lwdS = 3, side = c("top", "bottom", "none"), csub = 1, ...)
x |
an object of class enfa |
xax |
the column number for the x-axis |
yax |
the column number for the y-axis |
h |
vector of bandwidths for x and y directions, used in the
function kde2d of the package MASS . Defaults to
normal reference bandwidth (see ?kde2d ) |
pts |
logical. Whether the points should be drawn. If
FALSE , contours of kernel densities estimates are displayed |
ncont |
if pts == FALSE , an integer indicating the number
of contour levels desired for the kernel densities estimates. By
default, only the external one is displayed |
clabel |
a character size for the columns |
colZ |
color for the kernel density estimates of the available pixels |
colS |
color for the kernel density estimates of the used pixels |
lwdZ |
if pts==FALSE , the line width for the kernel
density estimates of the available pixels |
lwdS |
if pts==FALSE , the line width for the kernel
density estimates of the used pixels |
side |
if "top" , the legend of the kept axis is upside, if
"bottom" it is downside, if "none" no legend |
csub |
a character size for the legend |
... |
further arguments passed to or from other methods |
scatter.enfa
displays a factorial map of pixels, as well as the
projection of the vectors of the canonical basis multiplied by a
constant of rescaling.
The kept axes for the plot are specified in a corner.
biv.test
uses the function kde2d
of the package MASS
.
