senso.class {SensoMineR} | R Documentation |
Performs the scatter diagrams with representation of point classes.
senso.class(dfxy, fac, wt = rep(1, length(fac)), xax = 1, yax = 2, cstar = 1, cellipse = 0, axesell = TRUE, label = levels(fac), clabel = 1, cpoint = 0.5, pch = 20, col = rep(1, length(levels(fac))), col.moy = rep("blue",length(levels(fac))), xlim = NULL, ylim = NULL, grid = TRUE, addaxes = TRUE, origin = c(0,0), include.origin = TRUE, sub = "", csub = 0, possub = "bottomleft", cgrid = 1, pixmap = NULL, contour = NULL, area = NULL, add.plot = FALSE, box=TRUE)
dfxy |
a data frame containing the two columns for the axes |
fac |
a factor partitioning the rows of the data frame in classes |
wt |
a vector of the point weightings of the data frame used for computing the means (star centers) and the ellipses of dispersion |
xax |
the column number of x in dfxy |
yax |
the column number of y in dfxy |
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 point labels |
clabel |
if not NULL, a character size for the labels, used with par("cex")*clabel |
cpoint |
a character size for plotting the points, used with par("cex")*cpoint . If zero, no points are drawn |
pch |
if cpoint > 0, an integer specifying the symbol or the single character to be used in plotting points |
col |
a vector of colors used to draw each class in a different color |
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 par("cex")*csub |
possub |
a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright") |
cgrid |
a character size, parameter used with par("cex")* cgrid to indicate the mesh of the grid |
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 line (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 |
box |
if TRUE draws a frame |
