[R] selecting subsets of data for analysis

[Brett Stansfield]

can you tell me how to ask R to analyse a subset of data

eg. supposing the data set consists of 9 columns and I only want R to
analyse columns 1, 3 and 5 

how would I command R to conduct eg. boxplots of those variables only?

thanks
brett
