I just want to get the security description output. Here is the code below just to get the security values.
In my bloomberg terminal it gives the description of "Generic First Corn" so I expect this as a result.
library(Rblpapi)
blpConnect()
bdh <- bdh("c 1 comdty", c('px_last', 'px_open'), start.date=Sys.Date()-31)
print(bdh)
