indentation with DataFrames.jl pipelines

When writing data cleaning pipelines, I often find that single step requires more than 80 characters to do right, and to maintain readability, I split the expression over multiple lines....

IndexedTable from TextParse.csvread output

4

I couldn't find an example in the documentation for how one builds an `IndexedTable`, with column names, from the output of `TextParse.csvread`. This appears to work (took me a while...):...

reshaping?

8

What is a way of reshaping an `IndexedTable`? The common use case I have in mind is where a data `Column` contains a vector of strings, where the typical entry...

Would it make sense to define a `datalabels()` function, similar to `dimlabels()`: ``` datalabels{T,D,C,V}(::Type{IndexedTable{T,D,C,V}}) = fieldnames(eltype(V)) datalabels(t::IndexedTable) = datalabels(typeof(t)) ``` Not sure the name of this function feels exactly right...

confused by this root finding example

1

I have some code which calls a root finding step, via the `Roots` package that I'd like to be able to differentiate. It appears that whether `ForwardDiff` "works" in this...

slow/high allocation gradient with mapreduce and iterators

11

I've found that when I compute the gradient of a `mapreduce` expression whose inputs are slices, Zygote generates fast/low-allocation gradients. However, Zygote's gradient for the equivalent expression with iterator inputs...

Hessian type analysis mismatch

Hi Enzyme Team, I'm trying to compute a hessian (or a hessian-vector product) using Forward-over-Reverse, doing my best to follow what's in the documentation, but I'm crashing and can't tell...

Consider the example provided in the "Multiple Estimations" [vignette](https://lrberge.github.io/fixest/articles/multiple_estimations.html): ``` base = iris [names](https://rdrr.io/r/base/names.html)(base) = [c](https://rdrr.io/r/base/c.html)("y1", "y2", "x1", "x2", "species") res_multi = [feols](https://lrberge.github.io/fixest/reference/feols.html)([c](https://rdrr.io/r/base/c.html)(y1, y2) ~ x1 + [csw](https://lrberge.github.io/fixest/reference/stepwise.html)(x2, x2^2) |...

Simpler example of a hard crash during Forward-over-Reverse

Hi Enzyme Team, I cannot get this MWE, which I've structured as similar to the documentation for F-o-R as possible, to work. Any suggestions for how I might fix it?...

setindex doesn't seem to work as advertised

``` julia> using NamedTuples julia> NamedTuples.setindex(@NT(a=1, b=2), :b, "cde") (a = 1, b = 2) ``` I would have thought the result would be `(a = 1, b = "cde")`
