How to remove n number of identical characters from string in R

Question

I have a string in R where the words are interspaced with a random number of character \n:

mystring = c("hello\n\ni\n\n\n\n\nam\na\n\n\n\n\n\n\ndog")

I want to replace n number of repeating \n elements so that there is only a space character between words. I can currently do this as follows, but I want a tidier solution:

 mystring %>% 
    gsub("\n\n", "\n", .) %>% 
    gsub("\n\n", "\n", .) %>% 
    gsub("\n\n", "\n", .) %>% 
    gsub("\n", " ", .)

[1] "hello i am a dog"

What is the best way to achieve this?

Answer 1

We can use + to signify one or more repetitions

gsub("\n+", " ", mystring)
[1] "hello i am a dog"
