…de public from js/trove/* and arr/trove/*
- a (second) test that checks all values are raw-rows - one that checks that the raw-rows contain only tuples
- fixes a DeMorgan's law mistake in actually subtracting off row projections - introduces "reduced" QR decomposition (which I omitted earlier, thinking it wasn't relevant) -- in the context of least-squares regression, we typically have very tall and very narrow tables of data, and the reduced decomposition sticks to computing with matrices of that size, rather than square matrices the height of the table -- this changes the O() performance from something like O(height^3) to O(height*width^2), which can be drastically better. - includes explanatory links to the math being used
given a table, the input cols, and the output col. - multiple-regression-coeffs: returns list of coefficients - multiple-regression-table: returns coeffs as 2-col table - multiple-regression-fun: returns predictor function
multiple regression functions with table argument
- tables.arr: use annotation RawArrayOfRows for better err msgs #1758 - table.js: uses JSModule, so as to include type RawArrayOfRows - post-load-hooks.js, reactors.js: modify field access to table.js - test-tables.arr: update table-from-rows tests
Dbp table mismatch
I've added a new method to scatter- and line-plots (which support image-labels), `.use-image-sizes(use-size :: Boolean)`, to toggle whether the charts should show the images at full size (true) or scaled to the point-size (false)
analogous to image-scatter-chart, this places custom images instead of translucent dots. it is up to the caller to either scale the images down to match the point-size, or set the point-size up to match the image size
The origin for the line should be at x1, y1, but since the arguments to makeOverlayImage move the _background_ right and down, we need to reverse both. This will mean that the background goes left and up and the start of the line is at the right place.
As it turns out, if your line is in the "wrong direction", the previous code didn't work. You have to shift by the closest point to the origin.
Fix add-line overlay
note: we do not support spacing of grid lines, or minor gridlines
…dot plots" that used to be a post-processing hackaround
fix: type checking check operators with `because`
fix: handle polymorphic type alias applications
New feature: creating a directory tree
…terns for url or non-url
Improve errors for `csv-table-file` and `csv-table-url`
