Hello sir, many thanks for this video. I am new to r. when I used this guide to extract the day, month and year, I was able to create columns for them however, the entries were showing NA even the column where they were extracted from - this column data type is character. in format moth/ day/ year hours:minutes:seconds. How can i convert this column to date data type so that it will enable the entries to show.
Thanks
