I am trying to plot positions on a grid where the x and y axis equate to longitudinal and latitudinal co-prdinates respectively. As these co-ordinates are southings and westings, i need the origin of my graph to contain the two highest values of each co0ordinate, with the values decreasing in both respects along both axes - I cannot seem to find any function within r to allow me to do this.
Also, how can i avoid r automatically rescaling my data - my data points are not evenly clustered and I want the scalings on the x and y axes to be the same, so that they represent a true picture of the spatial scattering. R rescales the data to fit the best "square" in each case - misrepresenting the scaling of my data. I have looked at all the options within par() and axis() and nothing here appears appropriate. Thanks in advance.. Laura ______________________________________________ [EMAIL PROTECTED] mailing list https://www.stat.math.ethz.ch/mailman/listinfo/r-help
