Turning field values into column names in an R data frame

Question

Hello I have the following dataframe returned using the RBloomberg library:

> tt <- bdh(conn, secs, \"last price\", \"20110501\")
> tt
          tic         


        

Answer 1

Have a look at the dcast function in package reshape2:

library(reshape2)
dcast(tt, date ~ ticker)
