How about
txt <- paste(rep("this is a nice text
Hi,
May be this helps:
vec<- "this is a nice text with nice characters"
library(stringr)
vec2<-unlist(str_match_all(vec,"\\w+"))
#or
# vec2<-str_split(vec," ")[[1]]
res<-unique(lapply(vec2,function(x) which(!is.na(match(vec2,x)
names(res)<- unique(vec2)
res
#$this
#[1] 1
#
#$is
#[1] 2
#
#$
2 matches
