The `heatmap` plot type is useful for visualizing a matrix, but the cells are all transposed relative to how matrices are represented at the REPL. Additionally it is flipped so...

I suspect this isn't heatmap-specific, but that's the context in which I'm seeing it pop up. In a Juno Session, running ```julia using PlotlyJS X = rand(1025, 5000)' plot(heatmap(z=X)) ```...

perf

I'm not actually sure where the right place on the stack is to fix this, because it seems to cut across several layers. Here's an example - Say I want...

It looks like the functions given to `innerjoin` need to be `Union{Function, Type}`, which precludes callable objects. Would it be possible to remove that restriction? For some local code I...

It occurs to me that if you could add functions inside the expression and also specify a different reduction function than `+`, you could pretty much do arbitrary map-reduce style...

For example, for a Complex inner product the expression should look something like: ```julia x1 = randn(ComplexF64, 10) x2 = randn(ComplexF64, 10) @ein y[] := x1[i]' * x2[i] ``` (I'm...

It seems that the `@ein` macro doesn't like having constants included. Interestingly it seems to throw a different error depending on whether you're multiplying or adding. ```julia x = rand(10,...

I was figuring out how `@join` works and ended up trying this: ```julia df1 = DataFrame(id=[1, 2, 3, 6, 8, 9], val1 = rand(6)) df2 = DataFrame(id=1:10) @join(df1, df2, _.id,...

bug

For some reason the exception backtraces generated when queries are messed up don't have a description of what the error was. For instance: ```julia julia> aggdata = @from d in...

I'm trying to optimize a real-valued parameter to minimize a complex-valued least-squares problem. Here's a MWE that demonstrates the problem. The basic idea is that you have a signal (`x`)...
