a data frame containing the two columns for the axes
the column number of x in dfxy
the column number of y in dfxy
a vector of strings of characters for the point labels
if not NULL, a character size for the labels used with par("cex")*clabel
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.
if TRUE, labels are framed
a logical value indicating whether the arrows should be plotted
the fixed point in the graph space, by default c(0,0) the origin of axes. The arrows begin at cent.
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 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 legend 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
