rounding of numbers using R

Question

I want to convert the following numbers in this way I tried to use all possible methods but i am unable to get the value which i expected

value        round off value
0.0 - 4.9         0
5.0 - 5.9         6
6.0 - 6.9         7
7.0 - 7.9         8
8.0 - 8.9         9
9.0 - 10.0        10

The above table is for reference

expected output  eg :- roundup(5.0) = 6  ,roundup(6.9)=7

so your input numbers are numeric (e.g., 4.3) or they are represented as intervals? — Sandipan Dey, Feb 19 '17 at 06:42
No I am just giving reference but the expected output must be like eg :- roundup(5.0) = 6 ,roundup(6.9)=7 — Dr.jeon, Feb 19 '17 at 06:45
Try `roundup<-function(x) c(0,6:10)[findInterval(x,c(0,5:9))]`. — nicola, Feb 19 '17 at 06:53

You can try:

roundup<-function(x) c(0,6:10)[findInterval(x,c(0,5:9))]
roundup(c(5,6.9))
#[1] 6 7
