the column number for the x-axis
the column number for the y-axis
if cpoint > 0, an integer specifying the symbol or the
single character to be used in plotting points
a character size for plotting the points, used with
par("cex")*cpoint. If zero, no points are drawn
a neighbouring graph
a size for the neighbouring graph lines used with
par("lwd")*cneig
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
a character size, parameter used with par("cex")* 'cgrid' to indicate the mesh of the grid
a logical value indicating whether the point "origin" should be belonged to the graph space
the fixed point in the graph space, for example c(0,0) the origin axes
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")
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
