dot-sample: General table row sampling

In MazamaTimeSeries: Core Functionality for Environmental Time Series

General table row sampling

Description

This is a wrapper around sample to make it easy to select random rows from a table. Supports either integer (sampleSize) or fractional (sampleFraction) row sampling. For reproducible debugging, specify seed.

If both sampleSize and sampleFraction are specified, sampleSize takes precedence.

Specifying sampleSize greater than the number of rows in the dataframe or sampleFraction > 1 will use all rows.

Usage

.sample(data, sampleSize = NULL, sampleFraction = NULL, seed = NULL)

Arguments

data	Dataframe to be sampled.
sampleSize	Non-negative integer giving the number of rows to choose.
sampleFraction	Fraction of rows to sample.
seed	Integer passed to set.seed for reproducible sampling.

Value

A data.frame
