How to convert a sentence to word table in R

Question

 I want to separate the words from sentences to get row vector each. 

 I want no matter how large the sentence is, the row vector of each of the sentences will only be the words one time.

 So, how do I get this word table without repetition?

Answer 1

Try the following code:

sentence <- c("case sweden", "meeting minutes ht board meeting st march now also attachment added agenda today s board meeting", "draft meeting minutes board meeting final meeting minutes ht board meeting rd april")
dd <- read.table(text = paste(sentence, collapse = '\n'), fill = TRUE)
test <- cbind(sentence, dd)

or

cc <- read.table(text = paste(gsub('\n', '', sentence), collapse = '\n'), fill = TRUE)
test1 <- cbind(sentence, cc)
