Alas, you don't have a suffix2 object defined, but try this:

d1 <- one(prefix, roots)
d2 <- one(roots, suffix)
rbind(d1, d2)

To see a potential flaw in your function (as least as far as console
output is concerned), try
rbind(d1, one(roots, suffix))

HTH,

Let's say that I'm trying to write a functions that will allow me to
automate a process
where I examine all possible combinations of various string groupings. Each
time I run
the one function, I want to include the new values to the end of a data
frame. The data
frame will basically be one column with a lot of rows.

roots <- c("car insurance", "auto insurance")
prefix <- c("cheap", "budget")
suffix <- c("rate", "rates")

one <- function(x, y, z=0) {
? ? ?nu <- do.call(paste, expand.grid(x, y, z))
? ? ?mydf <- data.frame(nu)
? ? ?print(mydf)
}

one(roots, suffix2)
one(prefix, roots)
one(prefix, roots, suffix2)

The code above just replaces each value in the data frame each time I run
the one function.

How can I add the new values to the end of the data frame?

Help!

I'm running R 2.13 on Ubuntu 10.10
