Overlapping matches in R

Question

I have searched and was able to find this forum discussion for achieving the effect of overlapping matches.

I also found the following SO question speaking of findin

Answer 1

Another roundabout way of extracting the same information that I've done in the past is to replace the "match.length" with the "capture.length":

x <- c("ACCACCACCAC","ACCACCACCAC")
m <- gregexpr('(?=([AC]C))', x, perl=TRUE)
m <- lapply(m, function(i) {
       attr(i,"match.length") <- attr(i,"capture.length")
       i
     })
regmatches(x,m)

#[[1]]
#[1] "AC" "CC" "AC" "CC" "AC" "CC" "AC"
#
#[[2]]
#[1] "AC" "CC" "AC" "CC" "AC" "CC" "AC"
