gen_agreemat: Create Agreement Matrix
In baruuum/btoolbox: random toolbox

Creates an agreement matrix by comparing either the row or the columns of a matrix

1	gen_agreemat(x, dim = c("row", "col"), missing = 99L)

`x`	an integer matrix
`dim`	what dimensions to compare; must be either "row" or "column"; defaults to "row"
`missing`	value that should be treated as missing (defaults to 99). `NA` values are automatically transformed into missing values. If this is not desired assigning any other `integer` value to them will prevent this behavior.

Let X be a n\times k matrix. If comparison across rows is demended (i.e., dim = "row", the function returns a n\times n matrix where the (i,j)th element is the number of columns on which the ith and the jth row agree by having the same value.
