Regex to match any character repeated three or more times in R

问题

What is the Regex to match any character repeated three or more times in R (e.g. "aaargh", "arrrrrgh", "yesssssss")? I read the solution for Python, PHP and PCRE on Stack Overflow, but they don't seem to be applicable to R. Thanks.

We can use grep

 grep("(.)\\1{2,}", v1)

data

 v1 <- c("aaargh", "arrrrrgh", "yesssssss")
