Impute zero for NA values in financial fields, respecting form scope

Source: R/utils.R
impute_zero.Rd

For a given set of column names and a data frame, imputes zero for NA values in financial fields while respecting whether a field is available to 990-EZ filers. PC-scope fields (990 only) are imputed only for rows that are not 990-EZ filers. PZ-scope fields (990 + 990-EZ) are imputed for all rows. Rows where every financial variable is NA are left untouched.

Usage

impute_zero(dat, vars, ez_rows)

Arguments

dat

A data.frame (the working subset, not the full dataset).

vars

Character vector of financial column names to consider.

ez_rows

Logical vector (length nrow(dat)) marking 990-EZ rows, as returned by detect_ez_rows().

Value

The modified data.frame with zeros imputed where appropriate.

Examples

data( dat10k )
ez <- detect_ez_rows( dat10k )
dat_imp <- impute_zero( dat10k, vars = get_pc_fields(), ez_rows = ez )
