Details
basE91 (capital E for stylization) is a binary to ASCII encoding format created by Joachim Henke in 2005.
The overhead (extra bytes used relative to binary) is 22.97% on average. In comparison, base 64 encoding has an overhead of 33.33%.
The original encoding uses a dictionary of 91 out of 94 printable ASCII characters excluding - (dash), \ (backslash) and ' (single quote).
The original encoding does include double quote characters, which are less than ideal for strings in R. Therefore,
you can use the quote_character parameter to substitute dash or single quote.
Value
A string representation of the raw vector.
