Unlist a list of dataframes in R

Question

I have a list of dataframes that I have created using

list_dataframes = list(dataframe_1, dataframe_2...)

And now I wonder how to unlist this list.

I have searched for it and found this solution:

list2env(list_dataframes ,.GlobalEnv)

However, when using that solution, the following error arises:

Error in list2env(list_dataframes, .GlobalEnv) : 
  names(x) must be a character vector of the same length as x

Any idea why it's happening?

Thanks!

It should be a named list i.e. list(dataframe_1 = dataframe_1, ...` — akrun, May 23 '22 at 15:19
Why exactly do you want to unlist your list? It's normally much easier to work with data in a list rather than clobber your global environment with a bunch of variables. You might just be making things more difficult for yourself. — MrFlick, May 23 '22 at 15:23

The error is a result of passing a list without names

list2env(list(1, 2, 3), .GlobalEnv)

Error in list2env(list(1, 2, 3), .GlobalEnv) : names(x) must be a character vector of the same length as x

list2env(list(a= 1, b = 2, c = 3), .GlobalEnv)
<environment: R_GlobalEnv>
