Have IJulia honor set_default_plot_format

4

It would be nice if `set_default_plot_format(:png)` was working in IJulia. Not sure if this is a bug or feature request.

[Coord.cartesian](http://gadflyjl.org/stable/lib/coordinates/#Gadfly.Coord.cartesian) has a `raster` argument which as I understand from https://github.com/GiovineItalia/Gadfly.jl/issues/133 should rasterize the data saved in the SVG. However the following creates an SVG with one rectangle per pixel:...

Fast filter with do block syntax

7

The "slow" version of `filter` can be appealing for various reasons, I think one of them is that it enables the `do` block syntax. See [this discussion](https://discourse.julialang.org/t/dataframe-filtering-based-on-conditions-comparing-one-column-to-other-columns/70802/6) for an example...

Autogenerated suffixes can clash

1

I was bit by this issue in a case that looked like this: ```julia julia> df = DataFrame(x=1:3); julia> select(df, :x => (x->2x), :x => (x->3x)) ERROR: ArgumentError: duplicate output...

Sampling from prior using return value doesn't work with MvNormal

8

The [guide](https://turing.ml/dev/docs/using-turing/guide) shows how to sample from the prior using return values: ```julia @model function gdemo(x, y) s ~ InverseGamma(2, 3) m ~ Normal(0, sqrt(s)) x ~ Normal(m, sqrt(s)) y...

`solve_for` gives Float64 instead of rational solutions

3

For example the following gives Float64 instead of rational values: ```julia julia> @variables x y; julia> Symbolics.solve_for([x + y ~ 2, x - y ~ 1], [x, y]) 2-element Vector{Float64}:...

Chain as pipe argument

3

Parentheses are necessary to put a chain in a pipe. For example the following ```julia @chain DataFrame(a=1:3) begin select(:a) end |> display ``` fails with ``` ERROR: MethodError: no method...

LBFGS first step too large

4

I got a false convergence result minimizing `-logpdf(Normal(150, σ) , 147.9)` with L-BFGS . My σ is defined on [0, 50], so Turing.jl maps it to (-∞, ∞) using a...

Support repl_ast_transforms

1

This is to discuss the possible re-inclusion of `repl_ast_transforms` support (originally added in https://github.com/JuliaLang/IJulia.jl/pull/947 but reverted because of a bad interaction with Revise). Could it maybe be added back as...

Cannot use alpha with numeric color mapping

7

The following works fine: ```julia df = (x=1:3, y=1:3, c=1:3) plt = data(df) * mapping(:x, :y, color=:c => nonnumeric) * visual(alpha=0.5) draw(plt) ``` but if I remove the `nonnumeric` I...
