In corybrunson/context: Produce formal contexts (binary matrices) from data

Convert a frequency table (non-negative numeric matrix) to a matrix of the same dimensions containing at each position $(i,j)$ the value $1$ if the selected test statistic meets the provided cutoff threshold and $0$ otherwise. In the case of a chi-squared test, an entry in the result is 1 only if the corresponding entry in the input matrix was greater than expected.

binarize_matrix(x, stat, thres, test = NULL)

matrix_chisq(x)

matrix_ratio(x)

`x`	Numeric non-negative matrix.
`stat`	Character string. The test statistic, either `chisq` or `ratio`.
`thres`	Numeric. The cutoff threshold for the test statistic.
`test`	Function taking one argument `x` and giving logical output. If provided, used to determine whether an entry is assigned the value $1$ (if returns `TRUE`) or $0$ (`FALSE`).
