Hi there,

I have a data.frame (pwt6) which I would like to transform:

country	year	gdp
MEX	1950	2
MEX	1951	5
BOL	1950	4
BOL	1951	12
ITA	1950	45
ITA	1951	2

This should be the result:
year	MEX.gdp	BOL.gdp	ITA.gdp
1950	2		4		45
1951	5		12		2

Right now I have this code (better - no code):
country.label<-names(table(pwt6$country)) 
result<-data.frame(year=NULL)
 for(i in country.label)
   ?

Thanks for any help,
Patrick
