Subject: Working with regular expression
Hello again,
I was trying to extract the date element from a character vector using
Regular expression. Below is a sample what I was trying to do:
> Text <- c("asdf May 09 2009", "dsaf_01-01-2001")
> gsub("[a-zA-Z_]", "", Text)
[1] " 09 2009" "01-01-2001"
I basically have a long text and the task is to extract the date
element. My above strategy failed because I can not extract the month
for the first element.
Can somebody help me out?
Thanks and regards,
