Hello all,

Can anyone point me to a decent introduction to using the plotting and assorted graphics functions in R?
 
I keep getting simple errrors and I can't figure out why, for example:
 
> image(x,y,z)
Error in image.default(x, y, z) : dimensions of z are not length(x)(+1) times length(y)(+1)
> length(x)
[1] 206
> length(y)
[1] 40
> dim(z)
[1] 207  41

 
It seems to me as if R is wrong--the matrix z is obviously of length(x)+1 times length(y)+1--but just as obviously I'm missing something essential.  Are there any "newbie" guides out there for getting started?
TIA,
 
Pete
