## A simple text.
s <- String(" First sentence. Second sentence. ")
## ****5****0****5****0****5****0****5**
## Basic sentence and word token annotation for the text.
a <- c(Annotation(1 : 2,
rep.int("sentence", 2L),
c( 3L, 20L),
c(17L, 35L)),
Annotation(3 : 6,
rep.int("word", 4L),
c( 3L, 9L, 20L, 27L),
c( 7L, 16L, 25L, 34L)))
## Annotation for word tokens according to sentence:
annotations_in_spans(a[a$type == "word"], a[a$type == "sentence"])
