Dear David,
str_split_fixed calls str_locate_all, which gives
str_locate_all(ab, )
## [[1]]
## start end
## [1,] 1 0
## [2,] 2 1
##
in your example, since is a character of length 1. substring() is
probably more intuitive to get your expected result:
substring(ab, 1:2, 1:2)
FWIW this is fixed in the dev version of stringr which uses stringi
under the hood:
stringr::str_split_fixed('ab','',2)
[,1] [,2]
[1,] a b
stringr::str_split_fixed('ab','',3)
[,1] [,2] [,3]
[1,] a b

I'm puzzled as to why I get this behaviour with str_split_fixed in the
stringr package.
stringr::str_split_fixed('ab','',2)
[,1] [,2]
[1,]ab
stringr::str_split_fixed('ab','',3)
[,1] [,2] [,3]
[1,]a b
In the first example, I was expecting to get
[,1] [,2]
[1,] a b
