I have a vector like below:
vector
jdjss-jdhs--abc-bec-ndj
kdjska-kvjd-jfj-nej-ndjk
eknd-nend-neekd-nemd-nemdkd-nedke
How do I extract the last 3 values so that my result looks like below based on a - delimitor:
vector Col1 Col2 Col3
jdjss-jdhs--abc-bec-ndj abc bec ndj
kdjska-kvjd-jfj-nej-ndjk jfj nej ndjk
eknd-nend-neekd-nemd-nemdkd-nedke nemd nemdkd nedke
I've attemped to use sub and the qdap package but no luck.
sub( "(^[^-]+[-][^-]+)(.+$)", "\\2", df$vector)
qdap::char2end(df$vector, "-", 3)
Not sure how to go about doing this.
strcapture, as a base R corollary to the tidyr extract answer from Wiktor:
strcapture("([^-]*)-([^-]*)-([^-]*)$", df$vector, proto=list(Col1="",Col2="",Col3=""))
# Col1 Col2 Col3
#1 abc bec ndj
#2 jfj nej ndjk
#3 nemd nemdkd nedke
