R function to create data.frame based on variable in a column

I'm new to R and having some trouble. If I have a df call 'xyz' as below.

from the df above, I want to crate separate data frames named with variables in c1 such as:

data frame name 'x'

data frame name 'y'

data frame name 'z'

sorry if it is already answered but I couldn't find any good solution for now.

Since you are new to R its ideal to stick to base R. But keeping a dplyr option for future use as well.

df %>%
  group_by(`C1`) %>%
  group_walk( ~ write_csv(
    .x,
    paste0(
      "path_to_your_folder",
      "file_prefix_if_required_",
      .y$C1,
      ".csv"
    ) #paste0 function willbuild a custom filename as per your needs
  ), .keep = TRUE) #.keep=T will keep the grouped column in the file.

Pls check help on dplyr::group_walk and it has an example as well.
