Is posulbie to use lm() for two vectors"

```julia
julia>using GLM
 x=rand(10);

julia> y=rand(10);

julia> lm(x,y)
ERROR: MethodError: no method matching...

```

Just I cant to use DataFrames.  
Thanks, Paul

You need a two-dimensional array for `X`:

```julia
X = [ones(10) rand(10)]
y = rand(10) 
lm(X, y)

```
