How to convert character of percentage into numeric in R
I run into a problem when converting character of percentage to numeric. E.g. I want to convert "10%" into 10%, but
returns NA. Do you have any ideas?
10% is per definition not a numeric vector. Therefore, the answer NA is correct. You can convert a character vector containing these numbers to numeric in this fashion:
percent_vec = paste(1:100, "%", sep = "") as.numeric(sub("%", "", percent_vec))
This works by using sub to replace the % character by nothing.
