Hello,
Try the following.
# Create the dataset
Table1 <- matrix(10:6, ncol = 1)
rownames(Table1) <- letters[1:5]
Table1
t(outer(Table1[,1], Table1[,1], `-`))
Hope this helps,
Rui Barradas

Hello all,
i would like to calculate the difference of all row values and the others
row values from my matrix (table 1). The output (table 2) would be a matrix
with input matrix's row names on row names and colums names, thereby the
difference values among two of the row names could be bether found.
Could someone help me?
Examples:
Table 1:
a 10
b 9
c 8
d 7
e 6
Table 2:
a b c d e
a 0 -1 -2 -3 -4
b 1 0 -1 -2 -3
c 2 1 0 -1 -2
d 3 2 1 0 1
e 4 3 2 1 0
