Hi Karena,

As Remko mentioned, it really is polite to say what package your

function is from if its not one of the basics (such as base or stats).

Also, it is nice to give us sample data (side note, both of these

things are mentioned in the posting guide which you may find here:

http://www.r-project.org/posting-guide.html).

In any case I was able to search and find what is most likyle the

function you are using. Although it does not make particular sense,

here is an example plot with two sets of different lines added. They

incorporate results from running(), although the general plot() and

lines() function do not really care where the x and y values came

from.

library(gtools)

set.seed(1212)

dat <- runif(100)

plot(dat, running(dat, width = 5, pad = TRUE))

lines(dat, running(dat, width=10, fun = median, pad = TRUE))

lines(dat, running(dat, width=10, fun = mean, pad = TRUE), col = "blue")

HTH,

Josh
