6.14 Sub Strings in the Tidyverse
20180607 We will find ourselves often wanting to extract or modify sub-strings within a string. The tidy way to do this is with the stringr::str_sub() function. We can specify the start= and the end= of the string. The indices of the string start from 1.
## [1] "ring"## [1] "ring"A negative is used to count from the end of the string.
## [1] "string manip"Replacing a sub-string with another string is straightforward using the assignment operator.
## [1] "stipulation"The function also operates over a vector of strings.
## [1] "ring" "tion" "ways" "ting"## [1] "stRING" "manipulaRING" "alRING" "fascinaRING"If you find this curated material useful then you can consider a donation to support it's ongoing availability and give you access to the PDF version of this book.
