Numeric.
The distance tolerance set for automatic spell-correction purposes.
This function uses the function stringdist
to compute the Damerau-Levenshtein
(DL) distance, which is used to determine potential best guesses.
Unique words (i.e., n = 1) that are within the (distance) tolerance are
automatically output as best.guess
responses, which are then passed through
word.check.wrapper
. If there is more than one word
that is within or below the distance tolerance, then these will be provided as potential
options.
The recommended and default distance tolerance is tolerance = 1
,
which only spell corrects a word if there is only one word with a DL distance of 1.
