margin.table {base}

R Documentation

Compute table margin

Compute the sum of table entries over a given index.

margin.table(x, margin)

`x`	an array
`margin`	index number (1 for rows, etc.)

This is really just apply(x,margin,sum) packaged up for newbies.

The relevant marginal table.

m<-matrix(1:4,2)
margin.table(m,1)
margin.table(m,2)
