Sort function in R

Question

I am using the sort function on a particular column to rank hospitals based on a specific outcome.

The data ranges in value from 8.0 to 20.0.

However, when I use the sort function, instead of the lowest value appearing first, the data will be sorted with 10.0 first, followed by all data beginning with a 1, and will end with the lowest data (8.0, 8.1, 8.2).

Answer 1

> set.seed(1)
> s <- sample(seq(8, 20, by = 0.1), 20, TRUE)
> sort(s)
 [1]  8.7 10.1 10.4 10.4 11.2 12.5 12.5 12.6 14.0 14.9 15.6 15.9
[13] 16.3 16.6 17.3 17.4 18.8 18.9 19.4 20.0
> sort(as.character(s))
 [1] "10.1" "10.4" "10.4" "11.2" "12.5" "12.5" "12.6" "14"  
 [9] "14.9" "15.6" "15.9" "16.3" "16.6" "17.3" "17.4" "18.8"
[17] "18.9" "19.4" "20"   "8.7" 

Try something like this
