head(df)

#> 3 3rd   Male   Child No          35
#> 4 Crew  Male   Child No           0

How do I create a list of data frames that correspond to only one Class? In the above example, there are four different classes. So the list will contain four data frames. After that, I want to assign names to the list's elements. The names will be corresponding Class names.

Please note that I do not want to manually create the list and assign the names.

Why do you want to do this?
I mean: what are the next steps you want to do with this list of data.frames?

Write an excel file using writexl::write_xlsx(), each sheet will get the names from the list's names.

See e.g. https://statisticsglobe.com/r-split-data-frame-into-list-of-data-frames-based-on-id-column
For the 'next' part you could have a look at the purrr map variants.

Thank you! The following does the job!

split(df, f = df$Class)

I believe there are many other ways to achieve this. I hope somebody will share.
