One way to add the text is to use a list with named elements for the row and
column names:
> (M <- matrix(1:9, ncol=3, byrow=TRUE,
+ dimnames=list(" "=LETTERS[1:3],
+ "THIS IS AN EXAMPLE\nOF a 3x3 MATRIX"=LETTERS[1:3])) )
THIS IS AN EXAMPLE
OF a 3x3 MATRIX
A B C
A 1 2 3
B 4 5 6
C 7 8 9

Dear colleagues,
I would need to add text (some rows of information) in a matrix. For example,
given this matrix
1 2 3
4 5 6
7 8 9
I would need to add this info:
THIS IS AN EXAMPLE
OF a 3x3 MATRIX
1 2 3
4 5 6
7 8 9
I have been looking for a function that works similar to "fopen" in matlab, but
unfortunately I have not found It in R.
Thank you in advance for your help!
Carlos Fernandez
