Okay, I want to do something similar to SAS proc format.
I usually do this...
a <- NULL
a$divisionOld <- c(1,2,3,4,5)
divisionTable <- matrix(c(1, "New England",
2, "Middle Atlantic",
3, "East North Central",
4, "West North Central",
5, "South Atlantic"),
ncol=2, byrow=T)
a$divisionNew[match(a$divisionOld, divisionTable[,1])] <- divisionTable[,2]
But how do I handle the case where...
a$divisionOld <- c(0,1,2,3,4,5) #no format available for 0, this throws an
error.
OR
divisionTable <- matrix(c(1, "New England",
2, "Middle Atlantic",
3, "East North Central",
4, "West North Central",
5, "South Atlantic",
6, "East South Central",
7, "West South Central",
8, "Mountain",
9, "Pacific"),
ncol=2, byrow=T)
There are extra formats available... this throws a warning.
Thanks
Cory
