R help - Mar 2012 - create waveform sawtooth

Hi:

I am trying to create a sawtooth waveform. I used the following

x <- runif(500, min = -2, max = 2)
y <- (1 -abs(x3))* ((x3) <= 1)
combined <- data.frame(x = x3, y = y3)
plot(combined)

and I get a triangular waveform, not sawtooth. Can someone give a
solution to create a sawtooth waveform?

Thanks
deb

Perhaps something like this,

x <- seq(0, 10, length = 1000)
y <- x %%1

Or if people like a package:

library("tuneR")
st <- sawtooth(10)
plot(st)
