20180608 Formatting a text string into a neat paragraph of defined maximum width is another operation we often find ourselves wanting. The stringr::str_wrap() function will do this for us.
<- "All the Worlds a stage, All men are merely players" st cat(str_wrap(st, width=25))
## All the Worlds a stage, ## All men are merely ## players
Words of course form the basis for wrapping a sentence. We may wish to extract words from a sentence ourselves for further processing. Here we us stringr::word() to do so.We specify the positions of the word to be extracted from the setence. The default separator value is space.
<- c("The quick brown fox", "jumps on the brown dog") st word(st, start=1, end=2)
##  "The quick" "jumps on"
word(st, start=1, end=-2)
##  "The quick brown" "jumps on the brown"
