Hi! How can I make a spatial sample? Can someone recommend theorical books and materials for this? -- Raphael Saldanha UFJF - Brazil [[alternative HTML version deleted]]

...Gaussian / normal. But in order to check how "normal" the distribution is, I really need the y-axis to be Gaussian as well (meaning that the axis is not linearly scaled), so that if the distribution is indeed normal then the plot will be a straight line. I looked up cdf.plot (on the spsurvey package) and ecdf. They are both fine, but neither have any way (that I can see) to alter the scale on the y-axis so that it is not linear in the probability. How do I do this? As long as I am asking: I also want to plot more than one distribution or group. For instance, I want to plot 3 d...

Dear Sirs: I am not yet a user of R. My background includes the use of (Turbo) Pascal for scientific analysis of underwater acoustics problems (e.g. sound ray tracing and array gain in directional noise fields.) I have become interested in the following type of problem: (1) select , say, 1000 random locations within the continental United States; (2) characterize (statistically) the
