Draw uniform random (sub)sample

resample_uniform draws a random (sub)sample (with or without replacement) from the samples in data.

resample_uniform(data, param = list(n = Inf, replace = FALSE))

Arguments

data

a data.frame, rows represent samples

param

a list with the following components: n is a numeric value specifying the size of the subsample; replace determines if sampling is with or without replacement

Value

a data.frame containing a subset of the rows of data.

Details

If param$replace=FALSE, a subsample of size min(param$n,nrow(data)) will be drawn from data. If param$replace=TRUE, the size of the subsample is param$n.
