[julia-users] Multiplication and Division of DataFrame columns

[Jason Solack]

Hello everyone.  I have a DataFrame:

df = DataFrame(A=[1:10], B=[11:20])

i can add and subject the colums:

df[1]+df[2]

but if i multiply or divide i get errors.  Is there something special i 
have to do to muliply arrays?

Thank you in advance!
