In meghapsimatrix/SimHelpers: Helper Functions for Simulation Studies

Repeat an expression multiple times and (optionally) stack the results.

Description

Repeat an expression (usually involving random number generation) multiple times. Optionally, organize the results into a data.frame that stacks the output from all replications of the expression.

Usage

repeat_and_stack(n, expr, stack = TRUE)

Arguments

n	Number of times to repeat the expression
expr	An expression to be evaluated.
stack	Logical value indicating whether to organize the results into a data.frame.

Value

If stack = TRUE (the default), the results of each evaluation of expr will be stacked together using rbind. If stack = FALSE, a list of length n with entries corresponding to the output of each replication of expr.

Examples

repeat_and_stack(n = 3, data.frame(x = rexp(2)))

repeat_and_stack(n = 3, data.frame(x = rexp(2)), stack = FALSE)
