FF_FILL_NUMERATOR_DENOMINATOR Fill in missing values considering relationship between two variables — FF_FILL_NUMERATOR

Fill in based on relationship between NUMERATOR_c and DENOMINATOR_c. E.g., yield = production / area. NUMERATOR_c will be linearly interpolated forward then NUMERATOR_FILL_DIRECTION. Yield will be filled down-up, World average yield is used when only NUMERATOR_c or DENOMINATOR_c is available

Arguments

.DF: Input data frame

DENOMINATOR_c: DENOMINATOR col name (area) in the ratio
NUMERATOR_FILL_DIRECTION: Direction of filling in NUMERATOR

Value

A data frame with missing values filled
