expandDoubleVert: expand double-bar RE notation by splitting

Description

Modeled after lme4:::expandSlash, by Doug Bates. However, all formula operators that apply to factors (*, /, +) are applicable: the results are expanded into a list of independent (additive) random effect terms

Usage

expandDoubleVert(term)
RHSForm(formula) <- value
sumTerms(termList)
reOnly(f, response = FALSE, bracket = TRUE)
makeOp(x, y, op = NULL)
addForm0(f1, f2)
addForm(...)
expandAllGrpVar(bb)
findbars_x(
  term,
  debug = FALSE,
  specials = character(0),
  default.special = "us",
  target = "|",
  expand_doublevert_method = c("diag_special", "split")
)
inForm(form, value)
extractForm(term, value)
dropHead(term, value)
drop.special(x, value = quote(offset), preserve = NULL)
replaceForm(term, target, repl)

Value

a list of expressions

Arguments

term

expression/formula

formula

a formula object

value

term to remove from formula

termList

a list of formula terms

f

a formula

response

include response variable?

bracket

bracket-protect terms?

x

formula

y

a formula term (or an operator)

op

an operator

f1

formula #1

f2

formula #2

...

arguments to pass through to addForm0

bb

a list of naked grouping variables, i.e. 1 | f

debug

(logical) debug?

specials

list of special terms

default.special

character: special to use for parenthesized terms - i.e. random effects terms with unspecified structure

expand_doublevert_method

method for handling || operator: split into separate terms or replace by diag? Inherited from previous call where it was specified. 1. atom (not a call or an expression): NULL 2. special, i.e. foo(...) where "foo" is in specials: return term 3. parenthesized term: if the head of the head is | (i.e. it is of the form (xx|gg), then convert it to the default special type; we won't allow pathological cases like ((xx|gg)) ... [can we detect them?]

preserve

(integer) retain the specified occurrence of "value"

Examples

addForm0(y~x,~1)
addForm0(~x,~y)
ff <- lme4::findbars(y~1+(x|f/g))
expandAllGrpVar(ff)
expandAllGrpVar(quote(1|(f/g)/h))

expandAllGrpVar(quote(1|f*g))
expandAllGrpVar(quote(1|f+g))
expandAllGrpVar(quote(a+b|f+g+h*i))
## wish list ... this should be (1|a) + (1|a:b) + (1|a:b:c) + (1|a:b:d) ...
## expandAllGrpVar(quote(a/b/(c+d)))
expandAllGrpVar(quote(s(log(d), k = 4)))
