Title
Body
The documentation for str_split in the stringr package states that for the pattern argument: If "" splits into individual characters. which suggests it behaves the same as strsplit in this regard. However, library(stringr) str_split("abcab","") [[1]] [1] "" "a" "b" "c" "a" "b" with a leading empty string. This compares with, strsplit("abcab","") [[1]] [1] "a" "b" "c" "a" "b" Leading empty strings seems to be normal behavior when splitting on non-empty strings, strsplit("abcab","ab") [[1]] [1] "" "c" but even then, str_split generates an 'extra' trailing empty string: str_split("abcab","ab") [[1]] [1] "" "c" "" Is this discrepancy a bug, feature, an error in the documentation or just a different notion of what's 'expected behavior'?
