FAOSTAT (version 2.4.0)

scaleUnit: A function to standardize the unit

Description

The function standardize the data to the desirable unit when the multiplier vector is supplied. For example per 1000 people is scaled to per person by supplying a multiplier of 1000.

Usage

scaleUnit(df, multiplier)

Arguments

df

The data frame containing the data to be scale

multiplier

The named vector with the multiplier to be scaled. The name is mandatory in order for the function to identify the variable in the data frame. A data.frame can also be supplied with the first column being the name and the second being the numeric multiplier.

Examples

## Create the data frame
test.df = data.frame(FAOST_CODE = 1:5, Year = 1995:1999,
  var1 = 1:5, var2 = 5:1)

## Create the named vector for scaling
multiplier = c(1, 10)
names(multiplier) = c("var1", "var2")

## Scale the data
scaleUnit(test.df, multiplier = multiplier)
