Convert YYYY-YY to Year(date) in R : I have a data frame with year column as financial year 

Year  
2001-02  
2002-03  
2003-04  

How can I convert this to as.Date keeping either the whole thing or just the second year i.e 2002,2003,2004. On converting with %Y, I inevitably get 2001-08-08, 2002-08-08, 2003-08-08 etc. 

Thanks
