Subject: [R] regular expressions
Hello all,
Still fighting with regular expressions and such, I am again stuck:
Suppose I have a vector of character chains. In this vector,
I wish to identify which character chains start with a given
pattern, and then replace everything that comes after said pattern.
Here is a quick example :
words<-c("plifboum","plafboum","ploufbang","plifplaf")
I want to end up with something like this:
"plifONE","plafboum","ploufbang","plifONE"
All I can produce so far is this :
gsub("\\bplif.","ONE",words,perl=T)
which turns out :
"ONEboum","plafboum","ploufbang","ONEplaf"
Thanks in advance for your help.
