`blocks`	An optional specification for blocks of variables in the rows. The default assigns each variable in its own block.
`predictorMatrix`	A `predictorMatrix` specified by the user.
`data`	A `data.frame` with the source data

A list of formula's.

make.blocks, make.predictorMatrix

f1 <- make.formulas(nhanes)
f1
f2 <- make.formulas(nhanes, blocks = make.blocks(nhanes, "collect"))
f2

# for editing, it may be easier to work with the character vector
c1 <- as.character(f1)
c1

# fold it back into a formula list
f3 <- name.formulas(lapply(c1, as.formula))
