Float64 converting to complex when using globalEnv

[colintbowers]

Fantastic package! I was hoping to wrap some R statistical functionality from Julia and this is perfect. One issue I have encountered follows (in Julia):

using RCall
y = randn(10)
globalEnv[:y] = y
rcopy("typeof(y)")

returns "complex". One can easily get around this by inserting the additional line:

reval("y <- Re(y)")

But I thought I would raise it as an issue here just in case there are situations where this work-around will fail.

Cheers.
