enhancement request: pass list to set_values

[jonathan-g]

I am dealing with automating scraping from a form that has lots of checkboxes that I want to programmatically set.

Right now I'm doing

vals <- list(form = f)
vals[list_of_boxes_to_check] <- 'on'
f <- do.call(set_values, vals)

It would be nice to have a trailing-underscore variant set_values_, like the corresponding functions in dplyr with which I could do

vals <- set_names(rep('on', length(list_of_boxes_to_check)), list_of_boxes_to_check)
f <- set_values_(f, .dots = vals)

If there is not a reason why this would be a bad idea, I can implement it and submit a pull-request.

+1 for this feature but would be nice to keep the same function handle, just recognize if a list is input then apply it. Can also help with pull request if needed.

For anyone else with this issue, I've constructed a little wrapper for set_values that takes a list as input using do.call:

set_vals_batch <- function(form, .l) {
  do.call(function(...) {
    set_values(form, ...)
    }, .l)
}

This will likely be solved by switching from list() to list2() so you can do set_values(form, !!!vals)
