hi all,
I want to evaluate a function at each index of an array. There is a N
dimensional function, and I want to map it onto an N-dimensional array:
fpoly(x::Array{Real,5}) = x[1] + x[2]^2 + x[3] + x[4]^2 + x[5]
want to do
a = rand(2,2,2,2,2);
b = similar(a)
for i1 in indices(a,1)
for i2
Oh! Sorry I didn't get that. Thanks!

i'm trying to understand why we don't have something similar in terms of
comparison for Nullable as we have for DataArrays NAtype (below). point me
to the relevant github conversation, if any, is fine.
How would I implement methods to find the maximium of an
Array{Nullable{Float64}}? like so?
i see on the
docs http://docs.julialang.org/en/release-0.5/stdlib/simd-types/?highlight=SIMD
that there is a vecElement that is build for SIMD support. I don't
understand if as a user I should construct vecElement arrays and hope for
some SIMD optimization? thanks.

I'm getting the same error. This is making it really tough to get any
work done, since I can't seem to add, remove or update packages now.

I guess I'm looking for an iterator over the nonzero elements, ideally by
row. Does something like this exist? I know julia uses a different format,

hi simon,
very interesting to know indeed! I'll keep that in mind. thanks!

Hi!
I want to use the function interpolation suite from the GSL library. I came
across the GSL.jl package which wraps the entire GSL library (which is
awesome).
I am stuck with setting up the interpolation object and wanted to reach out
for help. my issue is described here in greater
detail:

I found this thread on integer powers, and it seems there are some benefits
of calling system pow() functions
(sometimes). https://github.com/JuliaLang/julia/issues/2741
is there anything related for non-integer powers or
. To be honest
I'm not sure if the manual is the right place for things like that - but it
would be good to have them in *some* place.

defined.
It's also possible to define your own orderings for special circumstances.
For example, DataFrames has it's own ordering for sorting the columns of a
DataFrame.

Hi,
say I want to use the GLM package to run a regression that contains several
categorical variables. My understanding is that I need the equivalent of an
R factor, which is a PooledDataArray. Suppose I take this dataset
using RDatasets
*data = dataset(Ecdat,Benefits)*
and I want columns
HI,
in this example, why do I get an InexactError() when showing the fit
summary? (I even converted :age to a Float)
*data = dataset(Ecdat,Benefits)**d2 = DataFrame(age =
convert(DataArray{Float64},data[:Age]), StateUR = data[:StateUR], sex =
convert(PooledDataArray,data[:Sex]))*
*julia
ok - got it. the pool!() function worked after a restart. not sure what
happened.
