I need to generate random numbers between 20 and 50 with 5 increments. For example, the numbers must be 20, 25, 30, 25, 50, 45 etc. The difference between numbers should be 5.
I tried this:
x<-floor(runif(50,20,50))
this gives me any number between 20 and 50. Is there an easy way to do this in R?

The runif() function generates random deviates of the uniform distribution and is written as runif(n, min = 0, max = 1) .
The R software provides access to the t-distribution by the dt() , pt() , qt() and rt() functions. Apply the help() function on these functions for further information. The rt() function generates random deviates of the t-distribution and is written as rt(n, df) . We may easily generate n number of random samples.
There are in-built functions in R to generate a set of random numbers from standard distributions like normal, uniform, binomial distributions, etc.
To create a random vector for a range of values, we can use sample function. We just need to pass the range and the sample size inside the sample function.
I think Arun was referring to this:
set.seed(123)
sample(seq(from = 20, to = 50, by = 5), size = 50, replace = TRUE)
# [1] 30 45 30 50 50 20 35 50 35 35 50 35 40 40 20 50 25 20 30 50 50 40 40 50 40
# [26] 40 35 40 30 25 50 50 40 45 20 35 45 25 30 25 20 30 30 30 25 20 25 35 25 50
