[R] Extending a vector

Looks fine to me. Why do you think the syntax is incorrect? Works for me in
1.8 on Windows.
> a <- 1
> a
[1] 1
> a <- c(a,2)
> a
[1] 1 2
> a <- c(a,2,4,5)
> a
[1] 1 2 2 4 5

Subject: [R] Extending a vector

I believe this should be an easy thing to do...

I have a function I repeatably call which takes input parameters and
outputs columns to various data frames. I also wish to keep a summary of
certain values as I call the function. I though keeping the values in a
vector then appending the vector by the new amounts would be the way to
do this.

Example: (this is what I want even thought the below syntax is wrong)

a <- 1
print(a) --> 1

a <- c(a,2)
print(a) --> 1,2

a <- c(a,2,4,5)
print(a) --> 1,2,2,4,5

Any help would be greatly appreciated...
