converting from Date format to another in R : <p>I want to convert my date format from 1/10/2017 to 2017-10-1 format using R. I tried using different methods as writhing a function or using Chron. I'm a beginner so any help would be appreciated.</p>

<p>note: if date is 1/8/2017 it should be converted to 2017-08-01</p>
