Plot of a frequency distribution
performs the scatter diagram of a frequency distribution.
s.distri(dfxy, dfdistri, xax = 1, yax = 2, cstar = 1,
cellipse = 1.5, axesell = TRUE, label = names(dfdistri),
clabel = 0, cpoint = 1, pch = 20, xlim = NULL, ylim = NULL,
grid = TRUE, addaxes = TRUE, origin = c(0,0),
include.origin = TRUE, sub = "", csub = 1, possub = "bottomleft",
cgrid = 1, pixmap = NULL, contour = NULL, area = NULL, add.plot = FALSE)dfxy |
a data frame containing two columns for the axes |
dfdistri |
a data frame containing the mass distributions in columns |
xax |
the column number for the x-axis |
yax |
the column number for the y-axis |
cstar |
a number between 0 and 1 which defines the length of the star size |
cellipse |
a positive coefficient for the inertia ellipse size |
axesell |
a logical value indicating whether the ellipse axes should be drawn |
label |
a vector of strings of characters for the distribution centers labels |
clabel |
if not NULL, a character size for the labels, used with |
cpoint |
a character size for plotting the points, used with |
pch |
if |
xlim |
the ranges to be encompassed by the x, if NULL they are computed |
ylim |
the ranges to be encompassed by the y, if NULL they are computed |
grid |
a logical value indicating whether a grid in the background of the plot should be drawn |
addaxes |
a logical value indicating whether the axes should be plotted |
origin |
the fixed point in the graph space, for example c(0,0) the origin axes |
include.origin |
a logical value indicating whether the point "origin" should be belonged to the graph space |
sub |
a string of characters to be inserted as legend |
csub |
a character size for the legend, used with |
possub |
a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright") |
cgrid |
a character size, parameter used with par("cex")* |
pixmap |
an object 'pixmap' displayed in the map background |
contour |
a data frame with 4 columns to plot the contour of the map : each row gives a segment (x1,y1,x2,y2) |
area |
a data frame of class 'area' to plot a set of surface units in contour |
add.plot |
if TRUE uses the current graphics window |
The matched call.
