> The following snippet currently leads to incomprehensible errors because we only support
matrix-frame casts but no scalar-frame casts. Since the frame gets dimensions 0,0 during compilation,
we also compile spark instructions for this conversion.
> {code}
> s1 = as.frame('foo')
> s2 = as.frame('bar')
> print (toString(s1))
> print (toString(s2))
> s = rbind(s1,s2)
> print (toString(s))
> {code}
