[R] how to produce 2-d color plots in R

[Yogesh K. Tiwari]

Hello 'R' Users,

I am very new on 'R', so excuse me if I ask something wrong.

I have ASCII data and the colums of the data are looks like :-


!-------------------------
time,yr,mo,dy,hr,min,sec,lat,lon,ht,co2obs,sigma,co2model
--
-
--

!----------------------------

Each column has data value. Now I want to produce 2-d color maps,
for example the plot should look like :-

on x-axis =lon    ,   on y-axis=lat

and on these two axis I want to shade  or fill co2model values.

Also, after ploting how I can draw the continent line, for
example the data belongs North America, so how the plot
recognise the continent line.

Can this type of color plot is possible in R.

Pls help !!!


Many thanks in advance,

Regarda,
Yogesh
