extracted.
OPTIONAL ARGUMENTS:
omit
an optional character vector with the names of variables to
be omitted from the returned formula. Defaults to c(".", "pi").
VALUE:
a one-sided linear formula with all variables named in the formulas
extracted from the objects in
..., except the ones listed in
omit
.
