Animated Statistics Using R (to be moved to AniWiki!)
Cluster sampling

Sometimes it is cheaper to 'cluster' the sample in some way e.g. by selecting respondents from certain areas only, or certain time-periods only. (Nearly all samples are in some sense 'clustered' in time - although this is rarely taken into account in the analysis.)

Implementations in R

There's a function sample.cluster() in the package animation for the demonstration of the cluster sampling. Please check the help file or the vignette of this package.
