Render RMarkdown document with multiple parameters using the purr::map function

Hello, I have an issue based on week1 tutorial. I want to create a table that contains all the parameters of the .Rmd document and then work down the table using purr::walk() producing RMarkdown documents for each row. I figured out how to do it for only one parameter ( player <- tibble( first_name = c("Roger", "Rafael"), filename = stringr::str_c(first_name, ".pdf"), params = purrr::map(first_name, ~ list(first_name = .)), )

player %>% select(output_file = filename, params = params) %>% purrr::pwalk(rmarkdown::render, input = "tutorial-01-suppC.Rmd") )

But when I try to expand to multiple parameters I get the following errors. Any help would be appreciated.

library(tidyverse)

player2 <- tibble(
  first_name = c("Roger", "Rafael"),
  last_name = c("Federer", "Nadal"),
  filename = stringr::str_c(first_name, ".pdf"), 
  first_param = purrr::map(first_name, ~ list(first_name = .)),
  last_param =  purrr::map(last_name, ~ list(last_name = .)),
  )

player2 %>%
  select(output_file = filename, params = c(player2$first_param, player2$last_param)) %>% 
  purrr::pwalk(rmarkdown::render, input = "tutorial-01-suppC .Rmd")

#> Error: Must subset columns with a valid subscript vector.
