Hi guys,

I have a dataset with about 32000 observations, which is in long
format (see structure below). gvkey is the identifier for a firm
(about 600 different firms), datadate is the monthend value between
2002 and 2010, which of course repeats in the dataset (again, long
format) and mcap_sum is my observation, which is different for each
month and gvkey.

gvkey	datadate	mcap_sum
212782	30jun2005	4946.9
212782	31jul2005	5042.1
212782	31aug2005	5145
212782	30sep2005	5302.5
212782	31oct2005	5253.5
212782	30nov2005	5642.7
212782	31dec2005	6230
etc...

Well, I would like to transpose my dataset so it shows each month as a
variable and the observations are mcap_sums. My tries with reshape
failed miserably. (xpose wont work because I still want to keep
mcap_sum as an observation).. Does anybody has a suggestion to solve
this quickly?

gvkey    31dec2005   30nov2005   31oct2005
212782  6230              5642.7           5253.5   ...........


Best,

Kaspar
