> x
[1] "TutorialsPoint is the largest online library for best tutorials"
> library(stringi)
> stri_sub(x,1,9)
[1] "Tutorials"
> stri_sub(x,1,-20)
[1] "TutorialsPoint is the largest online library"
> stri_sub(x,-14,-1)
[1] "best tutorials"
> stri_sub(x,-41,-1)
[1] "largest online library for best tutorials"
