Description

Sample a dataframe for n obs and returns full dataframe if n > nrow

Usage

sample_all_or_n(data, n, replace = FALSE, weight = NULL)

Arguments

data	A dataframe or tibble.
n	Number of rows to sample. If n is greater than the row count, the dataframe will be returned unchanged.

                A     = sample(c(NA_integer_, 1:3), size = 10, replace = TRUE),
                B     = sample(c(NA_integer_, 4:6), size = 10, replace = TRUE)
        )


# Sample less than row count
sample_all_or_n(data = test_data,
                n = 5)

# When n is greater than row count, the dataframe is returned unchanged
sample_all_or_n(data = test_data,
                n = 11)
