s.value {ade4} | R Documentation |
performs the scatter diagram with the representation of a value for a variable
s.value(dfxy, z, xax = 1, yax = 2, method = c("squaresize", "greylevel"), zmax=NULL, csize = 1, cpoint = 0, pch = 20, clegend = 0.75, neig = NULL, cneig = 1, xlim = NULL, ylim = NULL, grid = TRUE, addaxes = TRUE, cgrid = 0.75, include.origin = TRUE, origin = c(0,0), sub = "", csub = 1, possub = "topleft", pixmap = NULL, contour = NULL, area = NULL, add.plot = FALSE)
dfxy |
a data frame with two coordinates |
z |
a vector of the values corresponding to the rows of |
xax |
column for the x axis |
yax |
column for the y axis |
method |
a string of characters |
zmax |
a numeric value, equal by default to max(abs(z)), can be used to impose a common scale of the size of the squares to several drawings in the same device |
csize |
a size coefficient for symbols |
cpoint |
a character size for plotting the points, used with |
pch |
if |
clegend |
a character size for the legend used by |
neig |
a neighbouring graph |
cneig |
a size for the neighbouring graph lines used with |
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 |
cgrid |
a character size, parameter used with |
include.origin |
a logical value indicating whether the point "origin" should be belonged to the graph space |
origin |
the fixed point in the graph space, for example c(0,0) the origin axes |
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") |
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.
