Using .data[[.x]] or similar with pmap

[pcall]

Hi all,

I've written the code below which produces a data table of results based on a custom function I wrote, check_dart_score(). I'm trying to become more proficient with the purrr package, and would like to abstract this function to the pmap() series of functions.

However, I can't seem to figure out an equivalent in pmap() for the map() and map2 .data[[.x]] method. Would anyone be able to help me understand how these results can be achieved with pmap()? I've come across some conversations in GitHub that indicate the context of .data/.l doesn't exist within pmap, but I'm not sure how to make my code below work otherwise. Thanks!

map2_dfc(pull(dart_labels,1), pull(dart_labels,2), 
          ~dart %>% 
            check_dart_score(var = .data[[.x]], value = .y)
          )

Hi!

To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…
