Hello
I would appreciate any help with the following:
Given a matrix with col and row names, such as
> matrix1 <- matrix(rnorm(16),4)
> rownames(matrix1) <- LETTERS(1:4)
> colnames(matrix1) <- letters[1:4]
> matrix1
a b c d
A 1.6845882 -0.27809792 -0.874798414 -0.2143993
B -0.9283862 -1.50640703 -0.723568218 -0.4716539
C -1.6945380 -0.12336987 0.003299728 0.1413674
D -0.2715407 -0.05752609 -0.310539234 -1.1146264
I need to create a new matrix whose colnames are A-a, B-b, C-c and D-d. So
the col and rownames of matrix1 are separated by an hyphen.
It is probably very simple, but cannot find the way.
Thank you very much for your time.
