`reformulas`

(**r**andom
**e**ffects formulas) is a utility package for processing
“`lme4`

-style” random effects formulas in R (i.e., formulas
where the random effects are included in the form `(f|g)`

as
components of an overall model formula, where `f`

represents
a sub-formula for the varying effects and `g`

represents a
sub-formula for the grouping variable(s).

The package contains functions like `findbars`

(extract
terms containing `|`

, i.e. random-effects terms),
`nobars`

(drop terms containing bars from a formula), etc..
The goal of `reformulas`

is to be used upstream of
`lme4`

and `glmmTMB`

(and possibly other packages)
as a unified toolkit for processing formulas.
