  I have a data set in the following format: 
   
  x<-data.frame(id=c(‘a’,’b’,’c’),’2005-01-15’=c(100,225,425), ’2005-02-23’=c(1100,2325,4525))
   
  > x
    id X2005.01.15 X2005.02.23
  1  a         100        1100
  2  b         225        2325
  3  c         425        4525
   
   
  I want:
          id
    a
    b
    c
      X2005.01.15
    100
    225
    425
      X2005.02.23
