Split character vector into sentences [duplicate]

Answer 1

You could use the package tokenizers for that:

library(tokenizers)
tokenize_sentences(x)

where x is your character vector. It results in

[[1]]
[1] "This is a very long character vector."

[[2]]
[1] "Why is it so long?"                                                
[2] "I want to split this vector into senteces by using e.g. strssplit."

[[3]]
[1] "Can someone help me?"

[[4]]
[1] "That would be nice?"   

You could then use unlist to remove the list structure.
