grid
addaxes
origin
a data frame containing the two columns for the axes
a factor partioning the rows of the data frame in classes
the column number of x in dfxy
the column number of y in dfxy
the number of convex hulls and their interval
a vector of strings of characters for the point labels
if not NULL, a character size for the labels, used with par("cex")*clabel
a character size for plotting the points, used with par("cex")*cpoint. If
zero, no points are drawn
a vector of colors used to draw each class in a different color
the ranges to be encompassed by the x axis, if NULL, they are computed
the ranges to be encompassed by the y axis, if NULL they are computed
a logical value indicating whether a grid in the background of the plot should be
drawn
a logical value indicating whether the axes should be plotted
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
csub
possub
cgrid
pixmap
contour
area
add.plot
a string of characters to be inserted as legend
a character size for the legend, used with par("cex")*csub
a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft",
"bottomright")
a character size, parameter used with par("cex")* cgrid to indicate the mesh
of the grid
an object ’pixmap’ displayed in the map background
a data frame with 4 columns to plot the contour of the map : each row gives a
segment (x1,y1,x2,y2)
a data frame of class ’area’ to plot a set of surface units in contour
if TRUE uses the current graphics window
Value
The matched call.
