Controls How Lines Within a Diff Hunk Are Aligned
thresholdnumeric(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.
min.charsinteger(1L) positive, minimum number of characters that must
match across lines in order to align them. This requirement is in addition
to threshold and helps minimize spurious alignments. Defaults to
3.
count.alnum.onlylogical(1L) modifier for min.chars, whether to
count alpha numeric characters only. Helps reduce spurious alignment
caused by meta character sequences such as “[[1]]” that would
otherwise meet the min.chars limit
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")
