Hi All,,

I am trying to reshape some data from long to wide form

I have an id, temperature and a timepoint. However, id and timepoint are not unique, so I have ~1000 temperature readings for every time point for every id.

The data's current format
   id   month      temp
   -----------------------
 1     0        50
 1     0        55
 1     0        60
 1     3        20
 1     3        22
 1     3        33

How I want the data

   id       temp0		temp3	temp6
   -----------------------
 1     		50		20		12
 1     		55		22		12
 1              60 		.		11
 1     		55		20		12
 1     		.		33		12
 3		52		20		15


Any help with the command? When I use reshape wide temp, i(name ) j (op_time ) i get the error

op_time not unique within name;


Thanks,

Tina
