\description{
Controls How Lines Within a Diff Hunk Are Aligned
}
\section{Slots}{
\describe{
\item{\code{threshold}}{numeric(1L) between 0 and 1, what proportion of words
in the lines must match in order to align them. Set to 1 to effectively
turn aligning off. Defaults to 0.25.}
\item{\code{min.chars}}{integer(1L) positive, minimum number of characters that must
match across lines in order to align them. This requirement is in addition
to \code{threshold} and helps minimize spurious alignments. Defaults to
3.}
\item{\code{count.alnum.only}}{logical(1L) modifier for \code{min.chars}, whether to
count alpha numeric characters only. Helps reduce spurious alignment
caused by meta character sequences such as \dQuote{[[1]]} that would
otherwise meet the \code{min.chars} limit}
}}
\examples{
a1 <- AlignThreshold(threshold=0)
a2 <- AlignThreshold(threshold=1)
a3 <- AlignThreshold(threshold=0, min.chars=2)
## Note how "e f g" is aligned
diffChr(c("a b c e", "d e f g"), "D e f g", align=a1, pager="off")
## But now it is not
diffChr(c("a b c e", "d e f g"), "D e f g", align=a2, pager="off")
## "e f" are not enough chars to align
diffChr(c("a b c", "d e f"), "D e f", align=a1, pager="off")
## Override with min.chars, so now they align
diffChr(c("a b c", "d e f"), "D e f", align=a3, pager="off")
