How to produce random integer numbers from 0 - 100 but by 10s only?

Question

Using R (maybe runif() or sample()? ), how can one produce a set of integer random values? Lets say 100 random values from 0 - 100, but the values shou

Answer 1

One could select numbers uniformly from 0...10 and then multiply by 10. Sample code:

q <- 10*sample(seq(0,10), 1000, replace=TRUE)

Answer 2

sample will allow you to do the sampling easily. If we create a vector of the values we want it should be easy enough. seq(0,100,by=10) will allow us to construct a sequence starting at 0, ending at 100, by 10.

sample(seq(0,100,by=10), 100, replace = TRUE)
