Thanks to all who have provided me with valuable suggestions. I am
forging ahead now, and am beginning to enjoy R.
Thus spake Saurav Pathak:
+ I am trying to plot densities given on a two dimensional grid. My
+ data is in the an external file, and is arranged in three columns:
+ x, y, density
+ how may i get a plot of this? i would like to get (1) a three
+ dimensional plot and (2) a color coded two dimensional plot.
+ I have tried using
+ image(x, y, density)
+ but i am asked to put the data in ascending order. i am not sure
+ how i may put grid points in an ascending order.
+ I would also like to know if i could use any other function, other
+ than image.
+ thank you in advance.
