# Also vectorised over start and end
word(sentences[1], 1:3, -1)#> [1] "Jane saw a cat" "saw a cat"      "a cat"         word(sentences[1], 1, 1:4)#> [1] "Jane"           "Jane saw"       "Jane saw a"     "Jane saw a cat"

str <- 'abc.def..123.4568.999'
word(str, 1, sep = fixed('..'))#> [1] "abc.def"word(str, 2, sep = fixed('..'))#> [1] "123.4568.999"
