Scatter Plot

s.label.Rd

performs the scatter diagrams with labels.

Usage

s.label(dfxy, xax = 1, yax = 2, label = row.names(dfxy), 
    clabel = 1, pch = 20, cpoint = if (clabel == 0) 1 else 0, boxes = TRUE,
    neig = NULL, cneig = 2, xlim = NULL, ylim = NULL, grid = TRUE, 
    addaxes = TRUE, cgrid = 1, include.origin = TRUE, origin = c(0,0), 
    sub = "", csub = 1.25, possub = "bottomleft", pixmap = NULL, 
    contour = NULL, area = NULL, add.plot = FALSE)

Arguments

dfxy

a data frame with at least two coordinates

xax

the column number for the x-axis

yax

the column number for the y-axis

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

pch

if cpoint > 0, an integer specifying the symbol or the single character to be used in plotting points

cpoint

a character size for plotting the points, used with par("cex")*cpoint. If zero, no points are drawn

boxes

if TRUE, labels are framed

neig

a neighbouring graph

cneig

a size for the neighbouring graph lines used with par("lwd")*cneig

xlim

the ranges to be encompassed by the x axis, if NULL, they are computed

ylim

the ranges to be encompassed by the y axis, 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 par("cex")* cgrid to indicate the mesh of the grid

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 par("cex")*csub

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

Value

The matched call.
