In decisionpatterns/formula.tools: Programmatic Utilities for Manipulating Formulas, Expressions, Calls, Assignments and Other R Objects

• Ensure that magrittr operators are supported

• Does catcont and invert belong somewhere else?

• Create methods for append for signatures:

• expression, expression
• call, call
• expression, call
• call, expression

• "<-"

• Do these belong in vector.tools package?

• R/which.class

• test/is-cat.R

• expression.tools package(?)

• This should probably be called expression.tools rather than formula tool
• This packages handles calls and expression and assignments (only <- so far).
• A formula is also a call: is.call( a ~ b ) # [1] TRUE

• split.terms

• implement over custom operators. ? testing for %.+% on the first element ? test for name

• See if rhs, lhs, op, op.type are needed for other assignment operators: <<- ->

• Methods of class "<-" Break CRAN checks class( quote( A <- B) ) = "<-"

• [ ] Refactor to '_' syntax.

• Since so many of the function dispatch on single arguments, it might be worthwhile to redefine methods as S3 classes: is.one.sided; then again, it might be nice to allow multiple dispatch for replacement functions.
