[R] Repeating value occurence

[Nick Sabbe]

It is not exactly clear from your message what you want.
If you want n random values holding either -1, 0 or 1, use sample(c(-1,0,1),
10, replace=TRUE) or also sample(3, 10, replace=TRUE)-2
If you want n values following the pattern -1, 0, 1, 0 as your example seems
to follow, use
n<-10
pattern<- c(-1,0,1,0)
rep(pattern, ceiling(n/length(pattern)))[1:n]

If you want a sequence of random real numbers between -1 and 1, use
runif(10, min=-1, max=1)

Here's hoping I haven't just solved your homework...

Subject: [R] Repeating value occurence

How can achieve this in R using seq, or rep function

c(-1,0,1,0,-1,0,1,0,-1,0)

The range value is between-1 and 1,  and I want it such that there could be
n number of points between -1 and 1

Anyone? Please help Thanks
Rusty
