How about
txt <- paste(rep("this is a nice text with nice characters", 3), "But this is
not", collapse=" ")
library(stringr)
txt.vec <-str_split(txt, "[^[:alnum:]_]+")[[1]]
#vector of all the words in their original sequence
tapply(1:length(txt.vec), txt.vec, c)
#Returns a list of vectors of locations of each word, sorted
alphabetically
