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

layout(matrix(c(1, 2, 3, 2), 2, 2))

s.label(atlas$xy, lab = atlas$names.district,
area = atlas$area, inc = FALSE, addax = FALSE)
data(irishdata)
s.label(irishdata$xy, inc = FALSE, contour = irishdata$contour,
addax = FALSE)
par(mfrow = c(2, 2))
cha <- ls()
s.label(cbind.data.frame(runif(length(cha)),
runif(length(cha))), lab = cha)
x <- runif(50, -2, 2)
y <- runif(50, -2, 2)
z <- x^2 + y^2
s.label(data.frame(x, y), lab = as.character(z < 1))
s.label(data.frame(x, y), clab = 0, cpoi = 1, add.plot = TRUE)
symbols(0, 0, circles = 1, add = TRUE, inch = FALSE)
s.label(cbind.data.frame(runif(100, 0, 10), runif(100, 5, 12)),
incl = FALSE, clab = 0)
s.label(cbind.data.frame(runif(100, -3, 12),
runif(100, 2, 10)), cl = 0, cp = 2, include = FALSE)
