Re: [julia-users] Getting length of step range in function.

To be a little more explicit. You are "masking" the function `Base.length` with your local variable `length`. So when you write `length(range)` you are trying to "call" your local variable like it's a function. On Tue, Nov 10, 2015 at 9:47 AM, Yichao Yu wrote: > On Tue, Nov

Looks like the state of Julia's "Factors" (PooledDataArrays) is still quite a fast evolving monster. Because of this there hasn't been a proper implementation of R's "table" function. For now, if you want to run ChisqTest in Julia on two vectors do it on the matrix you would obtain in R by
