normalize: Normalize the values of the array by given margin
In beerda/hexmatrix: What the Package Does (One Line, Title Case)

Description Usage Arguments Value Examples

By normalization we understand dividing each value of the cell by a sum computed along the given MARGIN. The summation and division may be replaced with custom functions SUM and DIV, respectively.

1	normalize(x, MARGIN = seq_len(length(dim(x) - 1)), SUM = sum, DIV = `/`)

`x`	An array to be normalized
`MARGIN`	A margin, over which to perform the normalization.
`SUM`	The summationfunction
`DIV`	The division function

An array of dimensions equal to x with normalized values

m <- matrix(1:12, nrow=4)
r <- normalize(m, 1)   # normalize over the rows
rowSums(r)             # returns a vector of 1s
s <- normalize(m, 2)   # normalize over the columns
colSums(s)             # returns a vector of 1s
