Hello ,
 
 I am very new to R and I tried to find some solutions to my problem in 
the mail archives, but I couldnt.

 All I need to do is read a data file, which has data in " X Y Z " format 
and then I want to plot a surface plot or a contour plot of this.

my data is like ..

1710 0.626938723432     18.786
