Compile formulas needed to calculate one or more final indicators

Usage

calc_formulas_from_varname(varname = "pctlowinc", formulas = NULL, top = TRUE)

Arguments

varname: one or more character string variable names found in the "rname" column of the formulas parameter.
formulas: default is to use the built-in formulas_ejscreen_acs, but a custom data.frame can be supplied if it has columns "rname" and "formula".
top: do not change.

Value

data.frame with columns "rname" and "formula", similar to those columns as found in formulas_ejscreen_acs.

Details

Recursively finds formulas for any intermediate variables that are also outputs in the supplied formula table, then sorts them so dependencies are calculated before they are used.

Examples

EJAM:::calc_formulas_from_varname("pctlingiso")
EJAM:::calc_formulas_from_varname("pctlths")
EJAM:::calc_formulas_from_varname("pctlowinc")
EJAM:::calc_formulas_from_varname(c("lingiso", "lowinc"))
