Hello.
I have the following distance matrix between 8 points:
[1,] 0.00 3.162278 7.280110 8.544004 7.071068 9.899495 6.403124 8.062258
[2,] 3.162278 0.00 5.00 6.403124 4.472136 8.944272 6.082763 8.062258
[3,] 7.280110 5.00 0.00 1.414214 1.00 5.00 4.242641
Hello.
I have a matrix whit n1 rows and n2 columns called example.
If I do
image(example), R shows me an image with 480x480 pixels.
How can I obtain the gray level of the pixel of row i and column j?
Thanks,
Arnau.

Hello.
I want to create a list of vectors but each component of the list has a
different length.
For example:
Example=list()
Example=list(Example,c(1,2,3))
Example=list(Example,c(11,12,13,14,15))
If I want the first component of the Example list, I have to write:
Example[[1]][[2]]. R

Hello.
In the file list.txt, I have the name of n files in data frame format. I
want to make an image for each file and save the images in pdf format.
To do this, I do the following:
llista = scan(file=list.txt,what=list(nom=))
for (file.name in llista[[1]]){
