s.traject {ade4}

Trajectory Plot

Description

performs the scatter diagram with trajectories.

Usage

s.traject(dfxy, fac = factor(rep(1, nrow(dfxy))), 
    ord = (1:length(fac)),  xax = 1, yax = 2, label = levels(fac), 
    clabel = 1, cpoint = 1, pch = 20, xlim = NULL, ylim = NULL, 
    grid = TRUE, addaxes = TRUE, edge = TRUE, origin = c(0,0), 
    include.origin = TRUE, sub = "", csub = 1, possub = "bottomleft", 
    cgrid = 1, pixmap = NULL, contour = NULL, area = NULL, add.plot = FALSE)

Arguments

dfxy

a data frame containing two columns for the axes

fac

a factor partioning the rows of the data frame in classes

ord

a vector of length equal to fac. The trajectory is drawn in an ascending order of the ord values

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

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

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

edge

if TRUE the arrows are plotted, otherwhise only the segments

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

aan 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.

if(!adegraphicsLoaded()) {
  rw <- function(a) {
    x <- 0
    for(i in 1:49) x <- c(x, x[length(x)] + runif(1, -1, 1))
    x
  }
  y <- unlist(lapply(1:5, rw))
  x <- unlist(lapply(1:5, rw))
  z <- gl(5, 50)
  s.traject(data.frame(x, y), z, edge = FALSE)
