In decisionpatterns/data.table.plus: Extensions and Utilities for 'data.table'

TODO

• [x] Use mardown with roxygen

• [x] [set_]col_order function instead of setcolfirst; should:

• support partial list of columns
• allow placing at from or back

• allow SE or NSE

  set_col_order( dt, "colz", colb, ... )

• [ ] Fix foverlaps The problem with foverlaps is that it reverses the order of x and y. In DT, the normal join is a right-join ... i.e. everything in i of x[i, ...] For foverlaps, foverlap( x, y ... x is supposed to be the many small intervals table; A smarter overlap should keep the convention straight.

• Needed:

• Left Join that
• determines keys smartly
• prefixes smartly (?) -- nameit
• retains all columns from left and right side

• default values

• Maybe the stitching operation should be

• Create keys or X's without Y
• Stitch ADDITIONAL DIMENSION X's using RIGHT JOINS
• Add weighs as INNER JOIN on the right hand side
• Add Y('s?) as INNER JOIN on the right hand side

Completed

• [x] Think about how renameif relates to base.tools; moved to bt
