base91_encode {qs} | R Documentation

## basE91 Encoding

### Description

Encodes binary data (a raw vector) as ascii text using basE91 encoding format

### Usage

    base91_encode(rawdata)

### Arguments

`rawdata` | A raw vector

### Details

basE91 (capital E for stylization) is a binary to ascii encoding format created by Joachim Henke in 2005. The encoding has a dictionary using 91 out of 94 printable ASCII characters; excludes - (dash), \ (backslash) and ' (single quote). The overhead (extra bytes used relative to binary) is 22.97% on average. In comparison, base 64 encoding has an overhead of 33.33%. Because the dictionary includes double quotes, basE91 encoded data must be single quoted when stored as a string in R.
