s.match.class {ade4} | R Documentation |
Scatterplot of two sets of coordinates and a partionning into classes
Description
Performs a graphical representation of two sets of coordinates (different colors and symbols) and a partitionning into classes
Usage
s.match.class(df1xy, df2xy, fac, wt = rep(1/nrow(df1xy), nrow(df1xy)),
xax = 1, yax = 2, pch1 = 16, pch2 = 15, col1 = rep("lightgrey",
nlevels(fac)), col2 = rep("darkgrey", nlevels(fac)), cpoint = 1, label =
levels(fac), clabel = 1, cstar = 1, cellipse = 0, axesell = TRUE, 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
df1xy |
a dataframe with the first system of coordinates |
df2xy |
a dataframe with the secocnd system of coordinates |
fac |
a factor partitioning the rows of the data frame in classes |
wt |
a vector of weights |
xax |
a number indicating which column should be plotted on the x-axis |
yax |
a number indicating which column should be plotted on the x-axis |
pch1 |
if |
pch2 |
if |
col1 |
a color for symbols |
col2 |
a color for symbols |
cpoint |
a character size for plotting the points, used with |
label |
a vector of strings of characters for the couple labels |
clabel |
if not NULL, a character size for the labels, used with |
cstar |
a number between 0 and 1 which defines the length of the star size |
cellipse |
a positive coefficient for the inertia ellipse size |
axesell |
a logical value indicating whether the ellipse axes should be drawn |
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")* |
include.origin |
a logical value indicating whether the point "origin" should belong to the graph space |
origin |
a fixed point in the graph space, for example c(0,0) for the origin of 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 |
a |
contour |
a dataframe with 4 columns to plot the contour of the map : each row gives a segment (x1,y1,x2,y2) |
area |
a dataframe of class 'area' to plot an areal map |
add.plot |
if TRUE, add the plot to the current graphic device |
Value
The matched call.
