Is there a function to create character string of name-value pairs?

[arthur.t]

I have often had to write functions myself to create the facet titles or table titles for a combination of name-value pairs. See example below.

Is there a function somewhere that can do this? Perhaps with more options and generalizability?

library(tidyverse)

to_label <- function(x) {
  map2(names(x), x, str_c, sep = "=") %>% str_c(collapse = ", ")
}

list(a = 1, b = "two", c = FALSE) %>% to_label()
#> [1] "a=1, b=two, c=FALSE"

Hi,

As far as I know that doesn't exist, because if you'd use a list as in your example as input, the value could be anything, for example a data frame or nested list. Trying to collapse that into a vector would likely lead to issues.

Example that would lead to issues:

list(a = 1, b = "two", c = c(1, 2)) %>% to_label()
