Examples
junk <- factor(c(1,7,2,4,3,10))
str(junk)
#> Factor w/ 6 levels "1","2","3","4",..: 1 5 2 4 3 6
junk2 <- fact2num(junk)
str(junk2)
#> num [1:6] 1 7 2 4 3 10
## ONLY RUN IN INTERACTIVE MODE
if (interactive()) {
bad <- factor(c("A","B","C"))
# This will result in an error -- levels are not 'numeric'
bad2 <- fact2num(bad)
} ## END IF INTERACTIVE MODE
