Hi all,
I've found quite usefull colored-grid created by image() but I'm facing
a doubt I am not able to solve.
Given the following data rectangle...
1 2 3 4 5 6 7 8 9 10 11 12 13 14
1 12 22 0 7 2 1 0 2 0 2 6 -3 0 3
2 0 -1 0 9 3 -4 0 0 0 0 3 0 0 0
3 29 45 6 12 16 85 -2 0 -3 -4 89 -1 -1 1
4 2 9 3 6 17 3 -2 -9 -2 8 -1 0 0 0
5 44 16 -3 21 23 3 2 1 0 -2 13 18 -5 2
I am not able to draw x and y axis labeled 1 to 14 and 1 to 5 by 1. I've
tried a number of options by using axis() to no avail.
It will be also very helpfull to be able to draw the value of each x,y
combination within its position in the grid. Text() seems to be the answer, but
I am not able yet to get the correct position for each label.
Please, could you point me in the right direction or offer some example?
Thank you in advance,

If you data is a matrix, then try: image(1:5, 1:14, data.rect) text(row(data.rect), col(data.rect), data.rect) On 11/24/06, Ricardo Rodr?guez - Your XEN ICT Team <webmaster at xen.net> wrote:> Hi all, > > I've found quite usefull colored-grid created by image() but I'm facing a doubt I am not able to solve. > > Given the following data rectangle... > > 1 2 3 4 5 6 7 8 9 10 11 12 13 14 > 1 12 22 0 7 2 1 0 2 0 2 6 -3 0 3 > 2 0 -1 0 9 3 -4 0 0 0 0 3 0 0 0 > 3 29 45 6 12 16 85 -2 0 -3 -4 89 -1 -1 1 > 4 2 9 3 6 17 3 -2 -9 -2 8 -1 0 0 0 > 5 44 16 -3 21 23 3 2 1 0 -2 13 18 -5 2 > > I am not able to draw x and y axis labeled 1 to 14 and 1 to 5 by 1.
