[R] newbie question

Sorry - this must be obvious, but i haven't been able to find the answer in the guides i've searched. The examples seem to assume you always want to look at all the data.

I want to be able to filter data in a dataframe before analyzing it. For example, I'd like to plot(a,b) but only include values where b > 1000.

I'd also like to be able to do similar filtering before doing other statistical functions.

Thanks for your help.
