sample.strat {animation} | R Documentation |
Each rectangle stands for a stratum, and the simple random sampling without replacement is performed within each stratum. The points being sampled are marked out (by red circles by default).
sample.strat(pop = ceiling(10 * runif(10, 0.5, 1)), size = ceiling(pop * runif(length(pop), 0, 0.5)), p.col = c("blue", "red"), p.cex = c(1, 3), ...)
pop |
a vector for the size of each stratum in the population. |
size |
a corresponding vector for the sample size in each stratum (recycled if necessary). |
p.col, p.cex |
different colors /magnification rate to annotate the population and the sample |
... |
other arguments passed to |
None (invisible 'NULL
').
