How to remove certain special character occurrences from some elements in a vector?

Question

I have a vector filled with some numbers that I read from a .csv file, but some of those numbers are preceded by a * ,that is,

12 34 *89 *45 34

I want to remove the * from these elements while retaining their types, that is

12 34 89 45 34

How do I do this?

Answer 1

Try:

as.integer(stringi::stri_extract_all(x, regex = "[[:digit:]]+", simplify = TRUE))

Which gives:

#[1] 12 34 89 45 34
