I'm looking for a search function in R that will allow me to allocate values within ranges, or the equivalent of VLOOKUP in Excel.
Here is an example:
value <- c(5,4,3,2,1)
min <- c(381, 201, 97, 34, 0)
max <- c(NA, 380, 200, 96, 33)
tariffs <-data.frame(value=value, min=min, max=max)
> tariffs
value min max
1 5 381 NA
2 4 201 380
3 3 97 200
4 2 34 96
5 1 0 33
That is tariffs within the range (0,33) will receive a value of 1, within (34,96) the value of 2 and so on.
This would be the output for give tariffs:
tariff2019 <- data.frame(t19=c(779, 536, 368, 224, 96))
tariff2019$value <- c(5,5,4,4,2)
tariff2019
t19 value
1 779 5
2 536 5
3 368 4
4 224 4
5 96 2
How would I do this in R?
