binary_enc: Encode a character vector into a binary matrix

In lindberg-m/contextendR: Analyse genomic data with regard to sequence contexts

Description

Create a binary matrix for categorical data with optional noise

Usage

binary_enc(x, keys, as_equal = FALSE)

Arguments

x	The vector to be encoded
keys	The values to encode into
as_equal	Compare keys versus strings as being equal? Otherwise looks for the 'key' substring in x (default)

Details

The column of the resulting matrix will represent the encoded values, as specified in the keys parameter, retaining the order and accessible in the colnames of the resulting matrix. Note that elements of the keys parameter need to be unique. This function is used by fit_logistic_signature

Examples

 binary_enc(c('foo', 'bar', 'baz', 'bazinga'), c('foo', 'baz'))
 binary_enc(c('foo', 'bar', 'baz', 'bazinga'), c('foo', 'baz'), as_equal=TRUE)
