Subsample a paleontological time-series

Description

Subsampling is done according to the supplied logical vector or, if none is supplied, as a proportion of samples, randomly chosen.

Usage

sub.paleoTS(y, ok = NULL, k = 0.1, reset.time = TRUE)

Arguments

`y`	a `paleoTS` object
`ok`	a logical vector, `TRUE` for populations to retain
`k`	proportion of samples to retain, with the samples chosen randomly
`reset.time`	if TRUE, resets the time so that the first population time is zero

Value

the sub-sampled paleoTS object

Examples

x <- sim.GRW(ns=20)
plot(x)
xs1 <- sub.paleoTS(x, k = 0.5)
plot(xs1, add = TRUE, col="green")
keep <- rep(c(TRUE, FALSE), 10)
xs2 <- sub.paleoTS(x, ok = keep)
plot(xs2, add = TRUE, col = "red")
