Hi there,
I know, this question is not directly an R-help question but probably someone
can give me a hint how to deal with the following problem.
I have a vector with file/folder names and want to filter for all entries which
have 6 numbers in a row and nothing else.
folders <- c("folder1", "f2", "F234562", "12345678", "234567", "912345", "333")
I'd like to get only "234567" and "912345".
Can anybody help me creating a regex for this???
For example this regex:
regexpr("[^:digit:$]{6}", folders)
would match "F234562", "12345678", "234567", "912345"
