# Create data set with missing values
naDF <- data.frame(a = sample(c(1,2), 100, rep=TRUE), 
                   b = sample(c(3,4), 100, rep=TRUE), 
                   fNA = sample(c(100, 200, 300, 400, NA), 100, rep=TRUE))

# Created full data set
fillDF <- data.frame(a = c(1,2,1,2), 
                     b = c(3,3,4,4),
                     fFull = c(100, 200, 300, 400))

# Fill in missing f's from naDF with values from fillDF
FilledInData <- FillIn(naDF, fillDF, Var1 = "fNA", Var2 = "fFull", KeyVar = c("a", "b"))
