How to remove all line breaks (enter symbols) from the string using R?
I've tried gsub("\n", "", my_string)
, but it doesn't work, because new line and line break aren't equal.
Thank you!
回答1:
You need to strip \r
and \n
to remove carriage returns and new lines.
x <- "foo\nbar\rbaz\r\nquux"
gsub("[\r\n]", "", x)
## [1] "foobarbazquux"
Or
library(stringr)
str_replace_all(x, "[\r\n]" , "")
## [1] "foobarbazquux"

I just wanted to note here that if you want to insert spaces where you found newlines the best option is to use the following:
gsub("\r?\n|\r", " ", x)
which will insert only one space regardless whether the text contains \r\n
, \n
or \r
.
