s.arrowR Documentation

Plot of the factorial maps for the projection of a vector basis

Description

performs the scatter diagrams of the projection of a vector basis.

Usage

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

Arguments

dfxy

a data frame containing the two columns for the axes

xax

the column number of x in dfxy

yax

the column number of y in dfxy

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

edge

a logical value indicating whether the arrows should be plotted

origin

the fixed point in the graph space, by default c(0,0) the origin of axes. The arrows begin at cent.

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

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 legend 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.
