`setinterval` and `setball` should accept Float64, Float32.

time sequences with holes --> no holes in times, missings for data in introduced rows

This comes up as a question too often. Given an ordered *N* sequence of, say, DateTimes and data vectors each of *N* data values, DataFrames makes forming a frame of...

dimensional traits/predicates?

It would be useful to dispatch_on/query `isvector` `ismatrix` (without directly examining the type to find `N`, which may not exist).

I believe the result should be complex infinity.

infinity (+Inf and -Inf print as [+/- inf], 1//0 contains Inf)

``` AF = ArbField(123) posinf = AF("Inf"); neginf = -posinf; posinf > neginf, posinf, neginf (false, true, [+/- inf], [+/- inf]) altinf = AF(1)//AF(0) [+/- inf] altinf == posinf, altinf...

approaching better vectorization

@chriselrod @ffevotte I could use some help providing better vectorization over basic arithmetic ops for DoubleFloats. I have tried to follow the guidelines you have given without seeing much any...

powers of sums

This is a powerful and welcome tool. I would like to apply it to more packages. I have run into a limitation on supported types that seems more narrow than...

I have found it helpful to retrieve column(s) from an IndexedTable using `it[ colname]` or for multiple columns i`t[ [:ithciolname, :jthcolname] ]` I return an IndexedTable, but returning a Columns...
