Hello all I'm trying to index a dataframe in the folowing manner:
df = DataFrame(A = round(rand(1000) * 10), B = round(rand(1000) * 10))
df[:C] = 0
df[(df[:A] .== 1 & df[:B] .== 1),: C] = 1
I get an error "ERROR: no method &(Int64, DataArray{Float64, 1})
if i index like this, it works but i won't be able to do "ors"
df[(df[:A] .== 1 .* df[:B] .== 1),: C] = 1
is there another way of going about this?
Thank you,
Jason
