r - Aggregate, Date, Values -


I am new to R and am trying to gather results and am trying to find minimum dates. For example if I have 

  date of the ID value 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 -02 7 1 2013-12-02 9   
 I'm seeing the result as:  
  ID date value 2013-02-02 5 1 2013-04-02 7   
 Any time will be appreciated.   
 
 
 here  data.table   
  Library (Data Eligible) df $ date & lt; - as.Date (df $ date) is a solution with data. You can use  dplyr  (thanksgiving): (sd) [which.man (date),] = id   
  < pre>  library (dplyr) df%.% group_by (id)%.% filter (date == minute (date))   
 Both the output of something:    ID date value 1: 0 2013-02-02 5 2: 1 2013-04-02 7
