Dear R users,


I like to plot a matrix A which looks like this:


	,1		,2		,3		,4

1,	1		10		100		1000
2,	0.5		0.2		1.0		4.3
3,	0.1		0.2		0.3		0.5
	
.....


where the 1st row is representing the X-axis values. The subsequent  
rows should be plotted on the y-axis. I would prefer to use the  
smoothScatter plotting function of the geneplotter package, but to  
begin with R I'd be happy to use any scatterplot with the given  
dataset provided in the matrix A.

So I tried:

plot(A[1,],A[2:3,])

or

plot(A[1,],A[2-3,])

both result in :

Error in xy.coords(x, y, xlabel, ylabel, log) :
   'x' and 'y' lengths differ

What do I have to do?

Marek
