Hi, I was working on following expression :
"\":\"03-JAN-2018 16:00:00\"" This is basically a combination of Date and Time mixed with some Noise. I want to extract only Date and Time part i.e. "03-JAN-2018 16:00:00 I tried following : gsub("![0-9][0-9]-[a-zA-Z][a-zA-Z][a-zA-Z]-[0-9][0-9][0-9][0-9] [0-9][0-9]:[0-9][0-9]:[0-9][0-9]", "", "\":\"03-JAN-2018 16:00:00\"", ignore.case = TRUE) Obviously, with above code, I am removing that portion of my string which I actually I wanted! How can I reverse above code, so that I will be removing that portion of my string which I actually I ***NOT*** wanted? Thanks for your time.
