When reporting an Issue, please spend some time making it easy to follow and reproduce your issue. For this, I highly recommend using reprex package. You can also start a new Discussion to resolve an issue or share new ideas.
A good way to start is by contributing additional examples or improving the documentation. Additionally, you can submit a Pull Request to integrate your own function(s) in a new branch.
If you want to submit a new function please provide: the new function(s) with code and roxygen tags (with examples) as shown below
#' Add together two numbers
#'
#' @param x A number.
#' @param y A number.
#' @return The sum of \code{x} and \code{y}.
#' @examples
#' add(1, 1)
#' add(10, 1)
add <- function(x, y) {
x + y
}
